, p. 151/[451]-154/[454] (2005)
Several diarylethene derivatives having various substituents at the reactive carbons were prepared and the quantum yields were measured. Although the cyclization quantum yields were scarcely affected by the introduction of substituents, the cycloreversion quantum yields varied depending on the substituents.
Large geometrical structure changes of photochromic diarylethenes upon photoirradiation
Morimitsu, Kentaro,Kobatake, Seiya,Irie, Masahiro
, p. 1155 - 1158 (2007/10/03)
Photochromic diarylethene derivatives having phenylethynyl and pent-1-ynyl groups at the reactive carbons have been synthesized. These ethynyl groups enhance the cycloreversion quantum yields of diarylethenes without affecting the absorption maxima and th
