摘　　要：The emergence offlexible organic crystals changed the perception of molecu-lar crystals that were regarded as brittle entities over a long period of time,and sparked a great interest in exploring mechanically compliant organic crystalline materials toward next-generation smart materials during the past decade.Schiff base compounds are considered to be one of the most promising candidates forflexible organic crystals owing to their easy synthesis,high yield,stimuli respon-siveness and good mechanical properties.This paper gives an overview of the recent development of Schiff baseflexible organic crystals(including elastic organic crystals,plastic organic crystals,andflexible organic crystals integrating elastic-ity and plasticity)from serendipitous discovery to design strategies and versatile applications such as stimuli responses,optical waveguides,optoelectronic devices,biomimetic soft robots,and organic photonic integrated circuits.Notably,atomic force microscopy-micromanipulation technique has been utilized to bring the mul-tifunctional applications offlexible organic crystals from the macroscopic level to the microscopic world.Since understanding mechanicalflexibility at the molec-ular level through crystal engineering can assist us to trace down the structural origin of mechanical properties,we focus on the packing structures of various Schiff baseflexible organic crystals driven by non-covalent intermolecular inter-actions and their close correlation with mechanical behaviors.We hope that the information given here will help in the design of novelflexible organic crys-tals combined with other unique properties,and promote further research into the area of mechanically compliant organic crystalline materials toward multifunctional applications.
