Photochemical Reactions of Long-Chain Aromatic Conjugated Dienes and Anthracene Derivative in Langmuir-Blodgett Films

Abstract

Four kinds of amphiphilic aromatic compounds which one might expect to undergo efficient [2+2] or [4+4] photocycloadditions have been prepared for the investigation on photochemical reactions in Langmuir-Blodgett films. The properties of monolayers were very sensitive to molecular structure. The strong interaction of chromophores in LB films showed remarkable shift in electronic spectra.
