摘　　要：如果一个物体(或分子)与其镜像无法通过旋转或平移完全重合,则称其为手性物体(或分子)。手性是自然界中普遍存在的基本特征。手性材料具备圆二色性(CD)、圆偏振发光(CPL)等独特的光学性质,在光催化、生物传感、光学器件等多个领域具有良好的应用前景。光子上转换(UC)是指吸收多个低能量光子并发射一个高能量光子,上转换发光纳米颗粒(UCNPs)可以通过稀土离子间的能级跃迁实现光子上转换。结合光子上转换的手性材料由于低能量近红外激发的优势,在光动力学治疗、生物成像等领域具有更大的应用潜力。本文介绍了上转换发光纳米颗粒的手性构建方法,总结了其手性应用,并对未来发展方向进行了展望。An object(or molecule)is said to be chiral if its mirror image cannot be fully coincident by rotation or translation.Chirality is a universal basic feature in nature.Chiral materials possess unique optical properties such as circular dichroism(CD)and circularly polarized luminescence(CPL),offering promising applications in various fields,including photocatalysis,biosensing,and optical devices.Photon upconversion(UC)refers to the process of absorbing multiple low-energy photons and emitting a single high-energy photon.Upconversion nanoparticles(UCNPs)achieve photon upconversion through energy level transitions among rare-earth ions.Chiral materials incorporating photon up-conversion exhibit greater application potential in areas such as photodynamic therapy and bioimaging,owing to the ad-vantage of low-energy near-infrared excitation.This paper introduces the chiral construction methods of upconversion nanoparticles,summarizes their chiral applications,and discusses prospects for future development.
