Phototropic compound

Abstract

Abstract PURPOSE:The titled phototropic compound, capable of phase transition to a liquid crystal accompanying photochemical reaction by irradiation with light within a specific wavelength and temperature ranges in the crystal state and applicable to optical memory, optical switching elements, etc. CONSTITUTION:An organic compound crystal obtained by epitaxially growing, e.g. 4-methoxy-2-hydroxybenzylidene-4'-butylaniline on 4-methoxy-2- hydroxybenzylidene-4'-bromoaniline. The resultant crystal is capable of phase transition into a liquid crystal by irradiation with light within a specific wavelength and temperature ranges and then returning to the crystal bebore the irradiation with light by cooling.
