Lvov, Andrey G. published the artcileSpectral properties and structure of unsymmetrical diarylethenes based on thiazole ring with hydrogen at the reactive carbon, Category: thiazole, the main research area is thiazole diarylethene preparation fluorescence DFT; Conformation; Diarylethene; Fluorescence; Photocyclization; Photoreaction; Reaction intermediate; Thermal stability.
Six new photoactive unsym. diarylethenes bearing thiazole ring with hydrogen at the reactive carbon atom were synthesized. Their structures were studied by DFT calculations and x-ray crystallog. All compounds undergo irreversible photochem. transformations under irradiation with UV light, proceeding through the photocyclization stage. Only some normal (thiophene, imidazole and pyrazole derivatives) and inverse type (oxazole derivative) diarylethenes form colored photoinduced isomers under UV. In polar acetonitrile these intermediates show relatively fast irreversible thermal reaction, while in nonpolar toluene slow cycloreversion to initial diarylethenes is the predominant process of these species.
