Studies of the Generation of Excited Singlet Products in the Oxidation of the -CO-CH- Containing Molecules. The Chemiluminescence of Acylcarbazoles

Direct chemiluminescence emissions have been found from the air oxidation of 3-acyl-9-methyl- (1), 3,6-diacyl-9-methyl- (2), and 9-acylcarbazoles (3) due to the generation of an excited singlet state of monocarboxylate ions (from 1 and 2) and the carbazole anion (from 3).The relative intensities vs. the reaction time for the luminescent reaction of 3-isobutyryl-9-methylcarbazole could be interpreted by a reaction scheme involving consecutive reactions.Using this reaction scheme, the values of the decomposition rate of intermediates at 30, 40, and 50 deg C were determined to be 0.19, 0.42, and 0.98 min-1 respectively, which were comparable to the values reported for the decomposition rates of isolated dioxetanes giving excited singlet products.
