Abstract
Novel photochromic fulgides on the base of 3-formyl(acetyl)indole and 2-formyl(acetyl)pyrrole were synthesized and studied. The mechanism of the photoinduced processes in solution and vacuum-deposited films inc ludes: photoreversible (E)-(Z)-isomerization, photo- and thermoreversi ble cyclizations with the formation of colored dihydrocarbazole and di hydroindoline derivatives which irreversibly convert into uncolored fo rm by 1,5-hydrogen shift reaction.
