, p. 1814 - 1816 (2003)
New photochromic 1,2-dihetarylethenes containing maleimide-bridged thieno[3,2-b]pyrrole fragments with aliphatic and aromatic substituents at the nitrogen atom were synthesized.
Photochromism of thienyl-containing dihetarylethenes with five-membered cyclic bridges
Barachevsky,Strokach,Krayushkin
, p. 181 - 186 (2007/10/03)
Spectral-kinetic characteristics of a number of new photochromic dihetaryethenes with different five-membered cyclic bridges are measured and discussed. It was shown that these characteristics depend on a bridge structure as well as a nature of substituents in the thienyl fragments.
