The photomechanical bending and photosalient effect of flexible crystals of an acylhydrazone†
Abstract
Elastically flexible photo-actuating organic molecular crystals can serve as potential candidates in regard to the design of multi-performance sensors or actuators. Here, we are reporting an acylhydrazone derivative whose elastically flexible crystals demonstrate photosalient effect, which is preceded by photomechanical bending. Results drawn from the kinematic analysis indicate that the two photomechanical effects can be controllably induced by the selection of a suitable power density of UV light.
