switching characteristics—primarily on the thermal stability, and a series of thermally stable oxime-based photochromic diarylcyclopentenones have been prepared. The results obtained suggest that the modifications of the ethene “bridge” are a promising way to tune the spectral parameters of diarylethenes in an accurate manner and thus to synthesize the photochromic compounds with desired properties.

A mechanistic study of the photochromicproperties and photodegradation processes of an asymmetrical diarylcyclopentenone bearing thiophene and benzothiophene units using stationary photolysis, nanosecond laser flash photolysis and time-resolved luminescence was performed. It was found that the light-induced reversible isomerization of (3-(2,5-dimethyltiophen-3-il)-2-(2-methyl-1-benzylthiophen-3-i
