Light-induced changes of optical and electrical properties in bent-core azo compounds.

Abstract

We have studied the optical and electrical properties of two bent-core substances with an azo linkage in their cores. Pump-probe laser studies, direct textural observations, and spectrophotometric recordings show an initial decrease of light transmission, which at larger light intensities (approximately 1 mW/mm2) is followed by a bleaching. Simultaneously… (More)
