Separation of Photoactive Conformers Based on Hindered Diarylethenes: Efficient Modulation in Photocyclization Quantum Yields

Li, WL; Jiao, CH; Li, X; Xie, YS; Nakatani, K; Tian, H; Zhu, WH ANGEWANDTE CHEMIE-INTERNATIONAL EDITION 2014, 53, 4603-4607.

Endowing both solvent independency and excellent thermal bistability, the benzobis(thiadiazole)-bridged diarylethene system provides an efficient approach to realize extremely high photocyclization quantum yields (phi(o-c), up to 90.6%) by both separating completely pure anti-parallel conformer and suppressing intramolecular charge transfer (ICT).
