Carbazole photoinitiators for the photopolymerization of unsaturated compounds are provided, having the formulae:
wherein:
R1 and R2 are each alkyl having from one to about eighteen carbon atoms; or are taken together to form alkylene having from about two to about twelve carbon atoms;
R3 is selected from the group consisting of hydrogen; alkyl having from one to about eighteen carbon atoms; and acyl having from about two to about twelve carbon atoms;
in which R5 is selected from the group consisting of hydrogen; alkyl and alkenyl having from one to about eighteen carbon atoms; and R6 and R7 are selected from the group consisting of alkyl; hydroxyalkyl having from one to about eighteen carbon atoms; and R6 and R7 taken together to form alkylene having from about two to about twelve carbon atoms; and oxadialkylene and iminodialkylene having from four to about twenty-four carbon atoms:
Y2 is selected from the group consisting of hydrogen. halogen, and nitro;
R4 is a direct linkage (-) or alkylene having from about two to about twelve carbon atoms;
in which:
R8 is alkylene having from about two to about twelve carbon atoms;
R9 and R10 are alkyl having from one to about eighteen carbon atoms; or are taken together to form alkylene having from about two to about twelve carbon atoms.

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
