Forty-First DOE Solar Photochemistry P.I. Meeting Proceedings of the Forty-First DOE Solar Photochemistry P.I. Meeting Gaithersburg Marriott Washingtonian Center Gaithersburg, Maryland June 3-5, 2019 Chemical Sciences, Geosciences, and Biosciences Division Office of Basic Energy Sciences Office of Science U.S. Department of Energy FOREWORD The 41st Department of Energy Solar Photochemistry Principal Investigators’ Meeting, sponsored by the Chemical Sciences, Geosciences, and Biosciences Division of the Office of Basic Energy Sciences, is being held June 3-5, 2019 at the Washingtonian Marriott in Gaithersburg, Maryland. These proceedings include the meeting agenda, abstracts of the formal presentations and posters, and a list of participants. The Solar Photochemistry Program supports fundamental, molecular-level research on solar energy capture and conversion in the condensed phase and at interfaces. This conference is the annual meeting of the grantees who conduct research with support from this Program. The gathering is intended to facilitate the exchange of ideas and foster collaboration among these researchers. The meeting this year features an invited presentation by Harry Atwater, Director of the Joint Center for Artificial Photosynthesis (JCAP). JCAP is the Department of Energy’s Fuels from Sunlight Energy Innovation Hub, a multi-investigator research and development center that was established in 2010 and renewed in 2015. Its mission is currently focused on creating a scientific foundation for the solar-driven conversion of carbon dioxide into renewable transportation fuels. Prof. Atwater will tell us about recent JCAP discoveries and research accomplishments. I would like to express my thanks to Justin Johnson who continues to spend part of his time as a detailee for the Solar Photochemistry Program, assisting with numerous critical behind-the- scenes tasks. Special appreciation also goes to Teresa Crockett of the Office of Basic Energy Sciences and Connie Lansdon of the Oak Ridge Institute for Science and Education for their assistance with logistics for this meeting. Finally, I am grateful to all of the participants in this meeting who have contributed so much to the continued success of the Solar Photochemistry Program.

Yang* Contribution from the Department of Chemistry, UniVersity of Chicago, Chicago, Illinois 60637 ReceiVed July 17, 1996X Abstract: The ground-state and the excited-state spectroscopic properties of four series of polymethylene-linked anthracene-dialkylaniline bichromophores were compared as a probe to the relationship between energetics and distance in photoinduced electron transfer (PET). The results demonstrate that, when the energy level of the charge- transfer (CT) state is lowered below that of the localized excited state by appropriate substituents, there is a strong electron-donor-acceptor (EDA) interaction in the ground state which is absent in other bichromophores. Absorption and fluorescence excitation studies revealed that there is an unusually strong EDA interaction in the ground state of A-2 which is absent in other members in the A series. When A-2 is excited directly into this EDA absorption, it exhibits two CT emissions, one at 490 nm and the other at 605 nm. The quantum yield (τf) and the lifetime (Φf) of the two emissions are dependent on the viscosity of the alkane solvent. The Φf and the τf of the 490 nm emission increased when the solvent viscosity was increased; however, those of the 605 nm emission remained essentially unchanged. The risetime of the 605 nm emission is 420 ps, but that of the 490 nm emission is instrument-function limiting.

  • Photochemistry
    Photochemistry 1.1 Introduction:- Photochemistry is concerned with reactions which are initiated by electronically excited molecules. Such molecules are produced by the absorption of suitable radiation in the visible and near ultraviolet region of the spectrum. Photochemistry is basic to the world we live in with sun as the central figure, the origin of life must have been a photochemical act. Simple gaseous molecules like methane, ammonia and carbon dioxide must have reacted photochemically to synthesize complex organic molecules like proteins and nucleic acids. Photobiology, the photochemistry of biological reactions, is a rapidly developing subject and helps in understanding the phenomenon of photosynthesis, phototaxin, photoperiodism, vision and mutagenic effects of light. The relevance of photochemistry also lies in its varied applications in science and technology. Synthetic organic photochemistry has provided methods for the manufacture of many chemicals which could not be produced by dark reactions. Some industrially viable photochemical syntheses include synthesis of vitamin D2 from ergosterol isolated from yeast, synthesis of caprolactum which is the monomer for Nylon 6, manufacture of cleaning solvents and synthesis of some antioxidants. Photoinitiated polymerization and photopolymerisation are used in photography, lithoprinting and manufacture of printed circuits for the electronic industry. The photophysical phenomena of flourescence and phosphorescence have found varied applications in fluorescent tube lights, TV screens, as luminescent dials for watches, as “optical brighteners” in white dress materials, as paints in advertisement hoardings and so on. Another revolutionary application of electronically excited molecular systems is laser technology. The two main processes, therefore, studied under photochemistry are: 1. Photophysical process 2. Photochemical process 1.

    Structure, Chemistry, and Energetics of Organic and Inorganic Adsorbates on Ga-Rich GaAs and GaP(001) Surfaces Thesis by Seokmin Jeon In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy CALIFORNIA INSTITUTE OF TECHNOLOGY Pasadena, California 2014 (Defended September 30, 2013) ii 2014 Seokmin Jeon All Rights Reserved iii “No Pain, No Gain.” iv ACKNOWLEDGEMENTS I remember my wonderful mood when I first visited Caltech as a prospective student. Just before I came to Caltech, I visited the Columbia University, New York for the same purpose. I found everything in Pasadena including weather and people’s attitudes was attractive to me in contrast to what I found in New York. Living and studying in this beautiful place has been my best pleasure. Many individuals have supported, helped, and encouraged me to complete my Ph.D. course at Caltech, so it is my great pleasure to acknowledge them. I would like to thank my advisor, Professor Harry Atwater for his guidance and support. Especially, I appreciate him for providing me a great deal of freedom and independence on my thesis research. He has also shown me the wisdom, leadership, and enthusiasm that a leading scientist owns. My thesis committee, Professors Bill Goddard, Nate Lewis, and Jack Beauchamp are also my role models. It was my pleasure and honor to be advised by such great scientists. Many people in the Atwater group have contributed to the successful completion of my thesis research. Particularly, I would like to thank Jeff Bosco, Victor Brar, Seyoon Kim, Samantha Wilson, Min Jang, Jim Fakonas, Dan Tuner-Evans, Chris Chen, Yulia Tolstova, Hal Emmer, John Lloyd, Carissa Eisler, Siying Peng, Sunita Darbe, Amanda Shing, Imogen Pryce, Michael Kelzenberg, Jonathan Grandidier, Marina Leite, Gerald Miller, Vivian Ferry, Stanley Burgos, Ryan Briggs, Andrew Leenheer, Greg Kimball, Adele Tamboli, Deidre O’Caroll, Domenico Pacifici, Davis Darvish, Morgan Putnam, and Matt Sheldon for sharing their knowledge and skills, having time to discuss about research and science, and being good friends.
