A Novel Photochemical Interfacial Approach to the Degradation of Hazardous Materials
Abstract
Two studies are described. The first involved the use of time resolved electron spin resonance as a mechanistic and spectroscopic probe of two fundamental reactions of ketone photochemistry: intermolecular hydrogen abstraction by the triplet state of benzophenone and triplet state alpha-cleavage of 1,3-diphenylacetone (dibenzyl ketone). It was found that the forces restricting the ground state conformations of these ketones also restrict the triplet state conformations. The second study used steady-state spectroscopies and laser flash photolysis techniques to define the mechanism involved in biologically and medicinally related compounds employed as anticancer agents and a compound called A2-E, a bis-retinoid found inocular cells, believed to be associated with age-related macular degeneration.
