Abstract
Abstract Ternary mixtures of a photochromic azobenzene guest, low molecular weight liquid crystal (LMWLC) and polymer liquid crystal (PLC) were used and their photochemical phase transition behaviors were explored with special Reference to the stability of the photochemically induced isotropic phase and the response to photoirradiation. It was found that the rate of the photochemical phase transition increased as the mole fraction of the LMWLC component increased, demonstrating that the response of the systems is improved in the presence of the LMWLC components. Furthermore, the stability of the photochemically stored image has been shown to be much improved in the presence of the PLC components. Results obtained in this study clearly indicate that the LMWLC/PLC mixtures are promising as hosts for the optical image recording devices.
