Synthesis and photochromic properties of hybrid molecules based on fullerene C60 and 3,3′-(cyclopent-1-ene-1,2-diyl)bis(5-chloro-2-methylthiophene)

Abstract

A series of C₆₀ adducts with azides derived from 3,3′-(cyclopent-1-ene-1,2-diyl)bis(5-chloro-2-methylthiophene) have been synthesized for the first time, and their photochromic properties have been studied. The effects of the structure of the spacer connecting the fullerene and dihetarylethene moieties and electronic structure of the fullerene skeleton on the efficiency of photoinduced transformations of the new hybrid molecules have been estimated.
