Abstract: Two photochromic coumarin-based dithienylethenes were synthesized by one-pot nucleophilic addition reaction of alkyne and phenol. Both diarylethenes exhibited reversible photochromism, but their conformation played an important role in their photochromic properties. The derivative with high… read more here.
