Bozzi, Anna published the artcilePhotodecomposition of substituted 4-diethylaminoazobenzenes under visible light irradiation in different solvents, Quality Control of 1821-27-8, the publication is Journal of Photochemistry and Photobiology, A: Chemistry (2002), 152(1-3), 193-197, database is CAplus.
The visible light-induced decomposition of two series of 4-diethylaminoazobenzenes has been studied in solvents of different polarity, in the presence and absence of O2, in order to clarify the reaction mechanism. Two different paths have been recognized, whose importance depends on the nature of the solvent; both involve the formation of organic free radicals. Decomposition is much faster in acetone than in the other solvents. A strong inhibiting effect of mol. oxygen has been observed in all cases.
