摘　　要：Structural coloration strategies are widely adopted in the living world to manipulate light,offering great inspiration for humans to address the challenges in creating advanced photonic materials with desired performance.Among the vast photonic structures in nature,chiral photonic crystals have drawn special attention owing to their intricate 3D structure,unique chiroptical properties,and potential applications in chiral optics,pigments,information storage,and so on.In this review,we focus on the research progress in clarifying the hierarchical structures and unique optical properties of chiral photonic crystal structures found in animals and plants,including cholesteric-like one-dimensional photonic crystals and chiral gyroid structures.We summarize various top-down and bottom-up methods to mimic the biological strategy to fabricate chiral photonic crystals with comparable or better performances than their bio-counterparts.The emerging applications in sustainable photonic pigments,polarized luminescence and lasers,information storage,chiroptical devices,sensors,and radiative cooling are highlighted.We hope this review will be helpful in the design and fabrication of multifunctional chiral photonic materials inspired by nature.结构色策略在自然界中被广泛应用于操控光线,这为人们设计具有特定性能的先进光子材料提供了重要启发.在自然界的众多光子结构中,手性光子晶体因其复杂的三维结构、独特的手性光学特性以及在手性光学、颜料、信息存储等领域的潜在应用而备受关注.在本综述中,我们重点探讨了动物和植物中手性光子晶体结构的多层次结构及其独特光学特性,包括胆甾相的一维手性光子晶体和手性旋转体结构.我们总结了多种模仿生物策略的自上而下和自下而上的制备方法,以构建性能可与自然手性光子晶体相媲美或更优的人工手性光子晶体.本文还重点介绍了手性光子晶体在可持续光子颜料、偏振发光与激光、信息存储、手性光学器件、传感器以及辐射冷却等新兴应用中的潜力.我们希望本综述能为基于自然启发的多功能手性光子材料的设计与制备提供帮助.
