title: Synthesis and photochromic properties of functional diarylethene with a 2,5-dihydrothiophene bridging unit.
abstract: A novel synthetic route to symmetric and nonsymmetric dithienylethene derivatives with a 2,5-dihydrothiophene bridging unit was described. A class of new functional photochromic compounds was prepared and showed photochromic properties similar to those of known diarylethenes. [reaction: see text]
