Control of Cycloreversion Quantum Yields of Diarylethenes by Introduction of Substituents at the Reactive Carbons
摘要:
Several diarylethene derivatives having various substituents at the reactive carbons were prepared and the quantum yields were measured. Although the cyclization quantum yields were scarcely affected by the introduction of substituents, the cycloreversion quantum yields varied depending on the substituents.

Photochromic dithienylethenes that possess elements of lipid complementarity, and undergo large, photoinduced changes in molecular geometry have been prepared. Further, a regioselective approach has been developed for the preparation of dithienylethenes containing phenylethynyl and various aryl substituents at C2 and C5 of the thiophene moieties, respectively. The prepared photochromic compounds were
