| Outline of Final Research Achievements |
In the present research, we aimed at the creation of molecularly integrated multi-responsive photochromic systems, and obtained the following achievements. (1) Construction of photochromic diarylethene systems possessing multiple fluorescent functional groups in a diarylethene molecule which show the switching of fluorescent properties upon photochromic reactions. (2) Construction of photochromic systems which can switch on/off the photochromic pehomena, or change the position of the absorption band continuously, by the photochromism of a spiropyran which can generate a strong acid by the third light. (3) Construction of a photochromic system with diarylethene incorporated in human serum albumin (HSA) to show the highly enantioselective photochromic ring closure when the HSA-diarylethene system is placed in the optimized artificial environment.
