Effects of aromatic stabilization energies of aryl rings of symmetrical diarylethenes

Effects of aromatic stabilization energies of aryl rings of symmetrical diarylethenes
Four symmetrical diarylethenes bearing a variable aryl unit were synthesized and their crystal structures and photochromic performances were systematically studied to elucidate the effects of the aromatic stabilization energy (ASE) of aryl units. Experimental results revealed strong correlations of the thermal stability, as well as cyclization quantum yield, photoconversion ratio, and molar absorption coefficient of the darylethenes with the ASE of aryl units.
