Abstract

Photochromic bisbenzothienylethene has two conformers, photo-reactive anti-parallel and inactive parallel ones. The cyclization quantum yield is dependent on the ratio of the two conformers. By the introduction of bulky substituents at 2-positions of the benzothiophene rings, the cyclization quantum yield increased along with the increase in the ratio of the anti-parallelconformer.
