Photochemical Energy Storage (Photosensitized Isomerization Of Norbornadiene To Quadricyclane By Copper(I) Complexes), Dennis J. Fife
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This research has focused on the sensitized photoisomerization step of a solar energy storage system based on the interconversion of norbornadiene (NBD) and quadricyclane (Q). Sensitizers studied in the photoisomerization were arylphosphine complexes of copper(I) halides [(Ph3P)3CuX, (MePh2P)3CuX, (DIPHOS)CuCl; X = Cl, Br, I and DIPHOS = Ph2P(CH2)2PPh2]. The lowest electronic excited state of the complexes can be an effective triplet energy sensitizer as evidenced by a maximum quantum yield of 1.0 with (MePh2P)3CuX. The sensitization mechanism of the L …

Beginning in the mid-1970's, the development of energy resources in the western United States created significant changes in the small, rural communities of this area. Many of the changes were the result of the rapid influx of population associated with industrial activities. It has long been recognized that communities subject to rapid growth have difficulty meeting the physical facility needs of their residents, such as housing, shopping and school facilities, and sewer and water services. In recent years, a growing recognition of the importance of the social effects of rapid community growth has also developed. These effects include the deterioration …
