Design and fabrication of macroscopic functional devices by molecular engineering is an emerging and effective strategy in exploration of advanced materials. Photoresponsive overcrowded alkene-based molecular motor (OAMM) is considered as one of the most promising molecular machines due to the unique rotary motion driven by light with high temporal and spatial precision. Amplifying the molecular rotary motions into macroscopic behaviors of photodirected systems links the molecular dynamics with macroscopic motions of materials, providing new opportunities to design novel materials and devices with a bottom-up strategy. In this review, recent developments of the light-responsive liquid crystal system triggered by OAMM will be summarized. The mechanism of amplification effect of liquid crystal matrix will be introduced first. Then progress of the OAMM-driven liquid crystal materials will be described including light-controlled photonic crystals, texture-tunable liquid crystal coating and microspheres, photoactuated soft robots, and dynamic optical devices. It is hoped that this review provides inspirations in design and exploration of light-driven soft matters and novel functional materials from molecular engineering to structural modification.

放大分子尺度旋转运动：过度拥挤的烯烃分子马达与液晶的结合

通过分子工程设计和制造宏观功能器件是探索先进材料的新兴且有效的策略。光响应过度拥挤的基于烯烃的分子电机（OAMM）由于具有高时间和空间精度的光驱动的独特旋转运动，被认为是最有前途的分子机器之一。将分子旋转运动放大为光导向系统的宏观行为，将分子动力学与材料的宏观运动联系起来，为采用自下而上的策略设计新型材料和器件提供了新的机会。在这篇综述中，将总结由 OAMM 触发的光响应液晶系统的最新进展。首先介绍液晶矩阵的放大作用机理。然后将描述 OAMM 驱动液晶材料的进展，包括光控光子晶体、纹理可调液晶涂层和微球、光驱动软机器人和动态光学器件。希望这篇综述能为从分子工程到结构修饰的光驱动软物质和新型功能材料的设计和探索提供启发。
