Xin Cheng, Huan Hu, Yu Wu, Zhimin Ma, Zhiyong Ma, Zhiyong Ma, Zhiyong Ma
Abstract
photo-induced formation and force-induced breaking of the intramolecular hydrogen bonds. As a control, HBIA@PU experiences no response to photo/force. Thus, HBIA-2OH is a rare mechanophore featuring photo-gated mechanochromism.
