Development of a practical photochemical energy storage system. Quarterly report

Description

A study of a series of copper(I) compounds which contain a strongly absorbing chromophore (e.g., CuBr(PPh/sub 3/)-(2,2'-bipyridine)) for use as sensitizers in photochemical energy storage systems is described. The generally low sensitization efficiencies of these compounds preclude their use as sensitizers in a practical photochemical energy storage system. Nevertheless, some interesting mechanistic information has emerged from this study, the full details of which are being written for publication. Also, the related compound, Ru(bipy)/sub 2/(NBD)/sup +2/, which features a norbornadiene molecule coordinated directly to a strongly absorbing metal containing fragment was examined. The original rationale for studying this compound was the ... continued below

Description

A study of a series of copper(I) compounds which contain a strongly absorbing chromophore (e.g., CuBr(PPh/sub 3/)-(2,2'-bipyridine)) for use as sensitizers in photochemical energy storage systems is described. The generally low sensitization efficiencies of these compounds preclude their use as sensitizers in a practical photochemical energy storage system. Nevertheless, some interesting mechanistic information has emerged from this study, the full details of which are being written for publication. Also, the related compound, Ru(bipy)/sub 2/(NBD)/sup +2/, which features a norbornadiene molecule coordinated directly to a strongly absorbing metal containing fragment was examined. The original rationale for studying this compound was the expectation that the absorption of visible light would result in the population of an electronically excited state in which the electron density of the NBD is considerably perturbed. Relaxation of this state could then occur by a pathway which leads to the rearranged product, quadricyclene. It was found, however, that the sensitization efficiency of this compound is quite low. A comprehensive study of the factors which affect the sensitization efficiencies of Ir(bipy)/sub 2/(bipy')OH/sub 2//sup +3/ is unerway. In order to elucidate the mechanism(s) by which organic sensitizers affect the conversion of norbornadiene to quadricyclene, a study to measure the actual rate constant for the sensitization process is underway. The status of the project is discussed.
