Investigations of Chemiluminescence and Oxidation Reactions.
Abstract
The research projects during this period were focused on the oxidation chemistry of singlet molecular oxygen and on the development of efficient chemiluminescent systems. Major accomplishments of our investigations include the following: 1) The first heterogeneous photosensitizer for the photochemical production of singlet oxygen in organic solvents was prepared. This material has since been produced commercially and sold under the tradename SENSITOX. Additional sensitizers have been synthesized for use in aqueous systems. 2) 1-Phospha-2,8,9-trioxaadamantane ozonide was found to decompose at ambient temperature to provide a convenient chemical source of singlet oxygen. 3) A new method for generation of chemiluminescence by the silica-catalyzed rearrangement of thermally stable endoperoxides to 1,2-dioxetanes was discovered in the laboratory. 4) A procedure for obtaining dramatic increases in the chemiluminescence efficiency of dioxetanes by employing silica catalysis was developed. 5) A study of substituent effects on the decomposition of 1,2-dioxetanes provided new insight into the mechanisms of light production by these peroxides. 6) A new technique for triggering the chemiluminescent decomposition of a stable 1,2-dioxetane was investigated.
