Original Abstract

In this paper two types of 4-aminoazobenzene derivatives were vapour deposited and investigated as nanosized films. The films were characterized by UV-VIS spectroscopy. Birefringence was induced in the films by pump lasers with wavelengths of 355 nm and 444 nm within the absorbance band of the azo chromophores used. Laser light at 635 nm was used to probe the photoinduced birefringence. The recording dynamics and temperature dependence of birefringence have been presented. It was found that 4-aminoazobenzene derivative nanosized films have good photoanisotropic properties for optoelectronic device application.
