Abstract

Cosensitization effects of polyphenylene compounds (PP) such as biphenyl (BP), terphenyls (o-, m-, p-TP), and phenanthrene (Phen) in photoinduced electron-transfer reactions were examined. The 9, 10-dicyanoanthracene (DCA)-sensitized cis-trans photoisomerization of 1, 2-bis (4-methoxyphenyl) cyclopropane (CP), which proceeds in a chain reaction via free radical cation of CP (CP+) as a chain carrier, was accelerated by adding PP, particularly ...
