A novel diarylethene photochromic compound is provided. The photochromic compound is capable of forming an amorphous thin film by itself through a coating method and has an excellent thermostability. The amorphous thin film of the photochromic compound can exhibit a large refractive index between the isomers of the photochromic compound. Thus, using such an amorphous thin film provides an optical function device suitable for an optical memory device and an optical switching device.
