Synthesis and photochromic properties of hybrid molecules based on fullerene C<Subscript>60</Subscript> and 3,3′-(cyclopent-1-ene-1,2-diyl)bis(5-chloro-2-methylthiophene)

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.     

Photochromic Systems with Dynamic Adaptive Photobleaching

Results of own investigations on photochromic systems bleaching reversibly under sun light depending on the intensity of excitant radiation are described. The results are aimed to be used for the development of camouflage coatings and civil cloths with photoinduced dynamic automatic color change.
