Abstract

Spectral, luminescent, and photochemical properties of the novel bifunctional compounds BF1 and BF2 based on indoline spiropyrans and o-hydroxyazomethines have been studied in solid media. In PMMA films and frozen solutions, redistribution of photoexcitation relaxation channels in favor of photochemical processes leading to photochromic products in the azomethine moiety and luminescence is observed as compared with liquid solutions.
