摘　　要：Counterfeiting-related crimes pose a serious threat to the economic interests,security,and health of governments,businesses,and consumers.The urgent need for advanced anticounterfeiting materials with multilevel security for information encryption and decryption has driven significant research in this area.Supramolecular luminescent materials are potential for anticounterfeiting owing to their dynamic and controllable optical properties.In this review,the strategies adopted for fabricating supramolecular fluorescent materials and their corresponding anticounterfeiting technologies have been discussed.Especially,the time-dependent luminescent materials,which were created by non-equilibrium supramolecular assemblies and exhibited significant changes in fluorescence intensity and wavelength over time,were highlighted for their unique dynamic feature.This feature endowed materials programmable properties on time dimension,allowing for automatic and spontaneous behavior.Consequently,a series of information encryption materials have been developed,including self-erasing fluorescence hydrogels and 4D codes,demonstrating an enhanced level of security.近年来,信息安全已成为备受关注的研究热点.然而,目前主流的防伪油墨通常基于结构单一且光学性能不可调控的化合物,这类材料在信息编码后难以修改,同时存在信息泄漏和易被伪造的问题.因此,开发兼具高保密性、安全性与使用简便性的先进防伪材料已成为亟待解决的关键科学问题.超分子发光材料凭借其光学性能调控的高度灵活性,在信息加密领域展现了重要的应用潜力.本文综述了超分子荧光防伪材料的通用制备策略,重点阐述了通过自组装技术构建刺激响应性、性能可调节性及环境适应性优异的发光材料的研究进展.此外,本文还讨论了多种基于荧光的防伪技术应用,包括荧光墨水、荧光三维码以及时间依赖性材料,特别是时间依赖性发光材料在信息加密领域的应用前景,为该领域的研究与发展提供了思路和参考.
