Two types of diarylethene, each of which contains a naphthalene and a thiophene ring, were synthesized, and their photochromic properties were studied. The photochromic properties are dependent on the bridge position of the thiophene ring. The cycloreversion of one of the closed forms of some of the diarylethenes occurred almost photon quantitatively, and the photochromic reactions were thermally irreversible, at least at room temperature.
