Paper Abstract

Five amphiphilic alpha- or beta-amino acid derivatives containing photoactive azobenzene moiety and bearing amide or sulfonamide functional groups were synthesized and mono- and multilayers, prepared by Langmuir-Blodgett technique, were investigated. The reversible photoisomerization processes in solutions of these derivatives were observed. Reversible trans/cis photoisomerization of 4-[4-(hexyl- palmitoylamino)- phenylazo]benzenesulfonyl-(beta) -alanine in multilayer assemblies has been observed on alternate irradiation with UV light (centered at 360 nm) and visible light (452 nm).
