Paper Abstract

The photoisomers of diarylethene and spiropyran photochromic chromophores are oriented in films of poly-methyl-methacrylate when photoisomerized by polarized light irradiation. Photo- orientation occurs in both the forth and back photoisomerization reactions. The apparent optical orientation is inverted, e.g. changes sign, for the ultra-violet versus the visible photochemical transitions of both of the chromophores studied.
