Two kinds of bi-functional photochromic compounds (SpAz1 and SpAz2) were synthesized with spirobenzopyran and azobenzene derivatives by esterification. In chloroform solution, a novel photochromic compound (SpAz2) showed four kinds of isomers depending on the wavelength of the irradiated light. It is suggested that SpAz2 has four digital codes for optical memory.
