Abstract

Novel quantum yields (QYs) of photochromic cyclization reactions are studied for 1,2-bis (2-methyl-5-phenyl-3-thienyl) perfluorocyclopentene (1) and 1,2-bis (2-methyl-1-benzothiophen-3-yl) perfluorocyclopentene (2). The difference of the QYs in crystals and hexane solution for the molecules 1 and 2 is explained by their initial geometries, the relaxation from the Franck-Condon states, the shapes of the potential energy surfaces of the ground state, and the geometry change by the large amplitude motions.
