Preparation of Monolayer Films Containing Biomimetic Photovoltaic Molecules and Their Study Using Scanning Probe Techniques @ Arizona State University
This award is made by the Office of Special Projects in the Chemistry Division under the Materials Synthesis and Processing Initiative. Molecule-sized photovoltaic devices will be designed and synthesized using the principles of natural photosynthesis. These devices will be incorporated into Langmuir-Blodgett films and self-assembled monolayers on metal surfaces, and studied using time-resolved optical techniques. Producing such organized assemblies will overcome low current yields due to inefficient separation of electrical charge and injection of charge across interfaces. A scanning photoelectrochemical microscopy probe will be developed, capable of measuring the photoelectrical response of small regions of the films, or even of individual molecules. %%% Materials based on monolayer films hold substantial promise for the fabrication of electronic devices in general and photovoltaics in particular.

Integrated Use of Nmr, Workstations and Modelling Software in Undergraduate Laboratory Experiments @ Arizona State University
9451116 Bieber The major goals of the project are to develop and perfect a number of NMR and molecular modeling experiments that are suitable for integration into the undergraduate chemistry curriculum. An NMR and molecular modeling software will be purchased. Several excellent NMR experiments have been designed and tested by faculty for the biophysical, inorganic, organic and physical chemistry laboratories. and more than a dozen undergraduate students are engaged in research projects that use NMR. Funding the proposed project will allow faculty to develop additional NMR experiments for undergraduate courses, will expose all majors and many non- majors to NMR, and will permit students to apply powerful molecular modelling tools to chemical problems. The project will make it feasible for other institutions which lack NMR instrumentation to carry out NMR data analyses and molecular modelling studies at modest cost, because NMR data, processing macros and documentation will be available from Arizona State University through electronic communication or in tape formats. By using electronic networks, the impact of the project will extend well beyond undergraduate instruction at Arizona State University.

Photochemical Studies of Fullerene-Based Multicomponent Molecular Assemblies @ Arizona State University
With this renewal proposal the Organic and Macromolecular Chemistry Program continues its support for the work of Drs. Devens J. Gust, Anna L. Moore, and Thomas A. Moore of the Department of Chemistry at Arizona State University in Tempe, Arizona. Initial studies will involve carotenoid/porphyrin/fullerene (C-P-C60) triads, with photoexcitation leading to long lived C.+-P-C60.- charge separated states. These will lead to large synthetic porphyrin arrays linked to fullerene electron acceptors. Linking spiropyrans is expected to lead to light-activated switches. Finally, a cell-like vesicle-based system for conversion of light energy to chemical potential will be developed.
The work is aimed at the synthesis and investigation of the next generation of molecular photochemical energy conversion apparatus, mimicing the elements of natural photosynthesis: electronic excitation, charge separation, a transmembrane proton gradient, and energy storage in chemical products. In addition to the fundamental understanding developed, there is a real potential for the development of practical photoelectronic devices, including switches activated by light, and cells which convert solar energy into stored chemical energy more efficiently than green plants. The project requires a combination of many skills and techniques (organic chemistry, spectroscopy, biochemistry, and quantum chemistry) and should provide excellent training for the students involved.

Orchestrating Photochemistry, Energy Transfer and Electron Transfer in Multichromophoric Molecular Systems @ Arizona State University
With this renewal proposal the Organic and Macromolecular Chemistry Program continues its support for the work of Drs. Devens J. Gust, Anna L. Moore, and Thomas A. Moore of the Department of Chemistry at Arizona State University in Tempe, Arizona. The research is aimed at the synthesis and investigation of molecular photochemical energy conversion devices, which mimic the elements of natural photosynthetic systems including photochemical excitation, charge separation, and energy storage. These goals will be accomplished through the synthesis of "Supermolecules" based on porphyrins, fullerenes, and carotenoid polyenes. These supramolecular species undergo photochemically induced electron transfer to produce long-lived energetic species. The molecules will be coupled to photochromic species that are isomerized by light into colored and colorless forms in order to create light activated molecular switches. This research by Professors Gust and coworkers has the potential of aiding the development of practical photoelectronic devices that are able to convert solar energy into stored chemical energy with an efficiency that rivals that of green plants.
With support from the Organic and Macromolecular Chemistry Program, Professor Gust and coworkers will carry out collaborations with coworkers at the undergraduate, graduate and postdoctoral levels. The project, which requires a combination of many skills and techniques including organic chemistry, spectroscopy, biochemistry, and quantum chemistry, will provide important interdisciplinary research training for the students involved. Although fundamental in nature, the research is expected to provide a basis for advances in solar energy utilization, molecule-based sensing, and data processing, storage and transmission, and for a better understanding of biological electron and energy transfer processes.

Lsamp Phase Iv (2006-2011) Western Alliance to Expand Student Opportunities (Waeso) @ Arizona State University
Project Summary: LSAMP Phase IV (2006-2011) Western Alliance to Expand Student Opportunities (WAESO) WAESO combines the efforts of an alliance of 35 colleges and universities, 8 professional organizations, 2 government laboratories, 9 educational organizations, 21 corporations, 147 academic and support programs, 500 resource individuals, approximately 85% of whom are scientists, engineers, and other faculty, and 15% administrators with just over 40% of these resource individuals being underrepresented minorities. Overall Objective: Phase IV WAESO is a comprehensive, concerted, sequenced effort that proposes to use LSAMP NSF funding for underrepresented undergraduate student activities, including the transition of college sophomores, juniors, and seniors toward graduate school and the development of high technology products with application or dissemination both regionally and nationally. Through the Bridges to the Doctorate program our LSAMP will continue our successful multidisciplinary faculty mentoring network to transition these students to STEM Ph.D. programs. Moreover, with NSF Alliance for Graduate Education and the Professoriate (AGEP) support, PHASE IV WAESO students will be assisted through the doctorate and even beyond to faculty status or careers in the corporate or government sectors. Based on the successes of Phase I and Phase II in doubling the number of graduates per year of our target population and being on pace for a similar doubling goal in Phase III, we propose to take on the formidable task of achieving B.S. degree rates reflective of our substantial underrepresented minority population. Using the information form the census bureau (http://www.census.gov) USA July 2004 reports for Arizona, New Mexico, Nevada, and Utah state that our region has a population which of the 12,370,000 people estimated in this report, 34% (compared with 28% nationally) are American Indian, African American, and Hispanic. In order to move much closer to achieving parity with the relatively stable overall STEM B.S. degree production rate for the proposed Phase IV cohort of 10,551, we propose the numerical goal in the year 2011 of 2,630 STEM B.S. degrees awarded to American Indian, African American, and Hispanic as accomplishing much towards achieving parity with our regional population of these Americans, which would result in a representation of greater than 25% and put us well on the way to successfully reaching parity. Specific Goals: Based on the tremendous success of our current WAESO LSAMP Phase III alliance that has been funded in part by a NSF cooperative agreements since 1990, we specifically propose to: (1) Further institutionalize our highly successful Phase III activities to ensure that alliance goals and objectives will continue to be achieved beyond NSF support; (2) Double once again the annual BS degree rate from a new (adjusted due to cohort membership changes) current baseline of 1,315 underrepresented student science, technology, engineering, and mathematics (STEM) BS degrees to 2,630 within five years (by 2011); (3) Further expand, sustain, and connect LSAMP BS graduates, especially LSAMP Bridge to the Doctorate fellowship students, with our MGE@MSA AGEP and other AGEPs nationally to create, enhance, and institutionalize permanent pathways to successful graduate study and academic careers. The intellectual merit of our proposed activity is that we will draw upon and expand our alliances large existing communities of underrepresented minority STEM scholar/researcher/teacher/mentors and student apprentice scholar/researcher/teacher/protgs working collaboratively to further structure and sustain a research-based hot house environment to create wide-spread regional systemic change with dramatically positive national implications and repercussions. The broader impacts of our proposed activity is to achieve and sustain a level of admission, development, graduation, placement, promotion, and tenure of baccalaureate, masters, doctoral, post-doctoral, junior faculty, and senior faculty underrepresented STEM scholars in proportion to the diversity of our society as a whole. We have strong reason to believe that our WAESO LSAMP alliance will become a national model for the strengthening and diversification of STEM students and faculty to ensure that the U.S. will continue to lead the world in research and technology despite the increasingly intense global competition of the 21st century.

Adaptation and Self-Regulation in Multichromophoric Molecules @ Arizona State University
The Organic and Macromolecular Chemistry Program in the Chemistry Division at the National Science Foundation supports Professors Devens J. Gust, Anna L. Moore and Thomas A. Moore of Arizona State University for a research project that involves the synthesis and study of complex molecules consisting of covalently linked chromophores, electron donors and acceptors, and photochromic molecules that change their structure upon exposure to light. Each of these components can exchange information with others via intramolecular energy and electron transfer. It is these interactions that will allow complex phenomena to emerge. Several different classes of molecular systems have been identified as most promising for study. In one of these systems, Professor Gust and his collaborators will design, synthesize, and spectroscopically investigate molecules that absorb light and convert it to electrochemical energy in the form of a charge-separated state, as occurs in photosynthetic reaction centers. In another, "molecular triodes" and related structures will be studied. In these, a light-induced output such as fluorescence or photoinduced charge separation will be modulated by a second wavelength of light that is also absorbed by the molecule. These molecules will be analogs of electronic triode amplifier tubes or transistors, and their design will challenge our understanding of the factors influencing intramolecular energy and electron transfer. And finally, it has been recently demonstrated that the earth's magnetic field affects the lifetime of biradical states formed by light-induced intramolecular electron transfer. This discovery may help uncover how birds and other mammals can navigate using the earth's magnetic field. However, the chemical basis of the observed effect is not yet understood. Professor Gust and collaborators will prepare and study new molecules designed to uncover the mechanism in collaboration with researchers at the University of Oxford.
Broader impacts of the proposed research will be results that lead to a better understanding of emergent phenomena, a topic that cuts across many fields of chemistry, physics and biology. The research will involve students at the undergraduate, graduate and postdoctoral levels. Of special importance is the training of students from groups traditionally underrepresented in chemistry. Some of the recruiting and training will be in collaboration with several units of WAESO, (Western Alliance to Expand Student Opportunities), an NSF-LSAMP program centered at Arizona State University. Additionally, formal and informal programs for exchange of research students will be instituted with several Latin American universities. Experience has shown that highly-talented, successful students from Latin America serve as excellent role models for domestic Hispanic students, giving them the guidance and confidence necessary to achieve their potential. Informal student exchange programs with several European universities are currently in place, and will be continued and expanded in the new project.

Materials World Network: Study At the Nanoscale of Photovoltaic Materials @ Arizona State University
This Materials World Network project is a collaboration of groups from Argentina, Canada, México and the US with the common goal of synthesizing and characterizing, at the single molecule/particle level, semiconductor-photosensitizer materials that can be used for photovoltaic and solar-to-fuel applications. Electron injection by photosensitizers into semiconductor materials has been studied extensively, mostly by electrochemical and spectroscopic techniques based on conventional measurements of bulk materials. These studies often reveal electron transfer processes that are both thermodynamically and kinetically indicative of heterogeneity in the sensitizer-semiconductor material. To characterize such heterogeneity we are systematically studying the electron transfer processes using single molecule/particle techniques. If sub-populations of sensitizer-semiconductor particles of high efficiency can be identified, it should be possible to distinguish structural features that make it so and thus improve the sensitizer-semiconductor material interface and overall performance of photovoltaic devices.
A contribution of the US team is the synthesis of sensitizer-semiconductor nanoparticle models. Initially, we will work with systems consisting of perylene-TiO2 and perylene-SnO2. With the experimental techniques in hand, the aim is to develop tetrapyrrole-based semiconductor models, which upon excitation of the sensitizer in the visible range, inject electrons into the semiconductor conduction band and thereby generate high oxidation potential (> 1.30 V vs. NHE) sensitizer radicals. High potential is necessary to drive water oxidation. In parallel with these systems, we plan to develop materials for photoanodes having a highly reducing output, needed for the reduction of H+ to H2. Conventional and novel single molecule/particle fluorescence spectroscopy (SMFS) methods will be used to study photoinduced electron transfer processes within the sensitizer-semiconductor nanoparticle models. In particular, we seek to identify distributions of electron transfer efficiencies as a function of parameters such as sensitizer-semiconductor nanoparticle separation distance, type of linkage, geometry and assembly methodology. Another objective of the project is to study the role played by the occupation of the semiconductor energy levels in the photoinduced electron transfer process. The main technique in this case will be the newly developed single molecule/particle spectroelectrochemistry (SMS-EC). The electrochemical aspect of the technique will be used to control the population of the energy levels of the semiconductor particles, while the SMFS aspect will be used to monitor the redox state(s) of the sensitizer(s) in individual molecules by detecting their fluorescence.
The common denominator is a solar-to-fuel project important to securing a sustainable energy future appropriate to each culture. Undergraduate and graduate students working on this integrated project are thinking and communicating across disciplines and national boundaries. This award is co-funded by DMR-EPM, DMR-OSP, and OISE Americas Region.

Igert: Solar Utilization Network (Sun) @ Arizona State University
This Integrative Graduate Education and Research Traineeship (IGERT) award focuses on the energy transition from the current fossil-fuel-based economy to one where solar energy harvested by means of photovoltaics, solar-thermal, and photosynthesis-driven bioenergy approaches will become a keystone in global human energy use. Scalability, efficiency and economy of these three technical solar energy conversion approaches, along with societal components such as sustainability policy and responsible energy use, will all be necessary for success. This program supports the interdisciplinary training of diverse student cohorts in multiple solar energy conversion areas at different scales, integrated with a policy and social understanding, thus educating the next generation of citizen-scientists, innovative thinkers and enlightened policy makers who can guide society toward a sustainable energy future.
Broader Impacts: In order to further enhance inclusion of students from all backgrounds, the SUN IGERT project will leverage agreements with schools and programs with significant enrollment of underrepresented groups, particularly Hispanics and Native Americans, to lower barriers for underrepresented minorities. Effective mentoring and use-inspired, application-oriented, integrative research projects will enhance retention in the program. This program will also provide the groundwork for a novel Energy Ph.D. program. Successes from our program can be emulated and adapted at other institutions nationally and globally, thus catalyzing the training of a much larger group of students who can shepherd society to a new, sustainable energy future.
IGERT is an NSF-wide program intended to meet the challenges of educating U.S. Ph.D. scientists and engineers with the interdisciplinary background, deep knowledge in a chosen discipline, and the technical, professional, and personal skills needed for the career demands of the future. The program is intended to establish new models for graduate education and training in a fertile environment for collaborative research that transcends traditional disciplinary boundaries, and to engage students in understanding the processes by which research is translated to innovations for societal benefit.

Western Alliance to Expand Student Opportunities (Waeso) to Parity Capstone Operational, Research, Evaluation, Documentation and Institutionalization 10+ Lsamp Alliance @ Arizona State University
This long-standing LSAMP activity was designed to support a strong and vibrant scientific and technological workforce through recruiting, retaining, and graduating scientists and engineers from currently underrepresented populations. The WASEO Alliance (one of the first projects sponsored by NSF?s Louis Stokes Alliances for Minority Participation) utilizes a multi-contextual approach involving project activities in student research experiences, the establishment of peer networks, an emphasis on the social context of science, and development of a culture of professionalism in students, to name a few areas. This multi-contextual approach will be tested scientifically and documented for scaling up nation-wide in order to continue our drive to increase the number of B.S. degrees earned annually by underrepresented minority science, technology, engineering, and mathematics (STEM) students. The project, in its final five years of NSF support (2016-2021), will seek to increase graduation rates in Arizona and Utah such that Alliance institutions will represent 33.8% of total bachelor?s degrees to minority STEM students in Arizona and Utah. That percentage would be roughly equal to today?s percentage of underrepresented minorities in the general population of those states.
The WAESO and its 13 Alliance partner institutions will continue to make improvements to its innovative research, teaching, and academic support interventions on behalf of undergraduate minority STEM students. These support interventions have been developed over the past 24 years and rated highly by external evaluation. In a very significant new addition, WAESO will initiate a major knowledge-generating, social science educational research project to scientifically study, test and evaluate the multi-contextual elements at work in order to determine their positive impacts on student advancement and faculty culture. The results of this research will contribute to our understanding of the positive changes in WAESO institutions as a result of the LSAMP program; and how the program components of the WAESO LSAMP lead to minority STEM student success. Project outcomes will, in turn, point the way toward a successful scaling of these best practices to a regional and national level.
