摘　　要：近年来,随着机械互锁分子领域的快速发展,化学家们开始尝试将发光基元引入机械互锁分子中,并探究其独特的发光性质.相比于发光小分子,机械键的存在使所得的功能化机械互锁分子表现出优异的发光性能.进一步地,通过巧妙地应用机械互锁分子独特的动态性,成功设计构筑了多样化具有突出刺激响应光学特性的机械互锁分子,并探索了其在光催化、光学传感、智能发光材料等领域的应用.此外,将手性元素引入机械互锁发光体系中,其圆偏振发光性能也引起了越来越多的关注.本文从机械键对发光性能的调控、刺激响应型机械互锁发光材料、手性机械互锁分子的圆偏振发光性能三方面综述了近年来基于机械互锁分子的新型发光材料的研究进展,并分析了当前面临的挑战,展望了未来该领域的发展前景.In recent years,along with the rapid development of mechanically interlocked molecules(MIMs),the introduction of luminescent elements into MIMs and the further explorations on their unique luminescence properties have attracted more and more attention.Compared with small luminescent molecules,the existence of mechanical bonds endows the resultant emissive MIMs with attractive luminescent properties.In addition,taking advantage of the unique dynamic feature of MIMs,the further construction of a variety of luminescent MIMs with stimuli-responsive emission behaviors have been successfully realized,which have showed wide potential applications in the fields of photocatalysis,optical sensing,and smart luminescent materials.Notably,the further introduction of chiral elements into mechanically interlocked luminescent molecules results in the successful construction of novel circularly polarized luminescence(CPL)-active materials.In this review,we summarized the recent research progress of mechanically interlocked luminescent molecules from the following three aspects:the regulation of luminescent properties through mechanical bonds,stimuli-responsive mechanically interlocked luminescent materials,and CPL-active chiral mechanically interlocked molecules,analyzed the current challenges,and prospected the future development directions in this field.
