Abstract

Some new azobenzene functionalized DMA-copolymers were prepared and their monolayers at the air-water interface characterized by (pi) -A isotherms. Measurements of second harmonic generation from floating and deposited monolayers were performed and the tilt angle and hyperpolarizability of the pendant NLO-phores in the polymer were derived. The apparently low value of the hyperpolarizability obtained for the active groups is attributed to interaction effects between the NLO-phores and their orientational distribution in the copolymer films.
