Abstract:

A series of novel photochromic compounds(4a—4d) based on spirooxazine and Schiff base residue were synthesized. Their structures were characterized by 1H NMR, 13C NMR, IR, and HRMS. The compounds were proved by UV testing to have excellent photochromic properties both in organic solutions and polymer films. The compounds(4a—4d) have shorter photoresponsive time and better photosensitivity than parent compound 3. We have also studied the kinetics of the thermal decay process of the representative compound 4b in methanol, DMSO, and several kinds of films, and presumed why there are two kinds of explains about the kinetics of the thermal decay process in the recent years. The representative compound 4d shows a good fatigue resistance. The applications of compounds 4a—4d in photo-fluorescent and photo-magnetic switch area are under investigation.
