Dithienylethenes with a Novel Photochromic Performance

Dithienylethenes with low decoloration quantum yields and thermal reversibility at high temperature above 100 °C were prepared. Introduction of bulky alkoxy substituents at 2- and 2‘-positions of the thiophene rings strongly suppressed the cycloreversion quantum yields. The quantum yields were lower...
