Fast and reversible bidirectional photomechanical response displayed by a flexible polycrystalline aggregate of a hydrazone

Abstract

In this study, a typical laboratory experiment was carried out to isolate the flat strips of a flexible polycrystalline aggregate of a hydrazone derivative. Due to the photoswitching ability of hydrazones, the material displays fast, reversible, and bidirectional photomechanical motion, unlike single crystals of the parent compound.
