摘　　要：有机长余辉发光材料具有制备方法简单、成本低廉、可柔性化、环境友好等优点,已广泛应用于防伪、信息保密、生物成像等领域。其中,基于掺杂体系的有机长余辉发光材料,可通过调控主客体之间的配位关系,实现长余辉时间和颜色的可调性,并可在室温下制备出性能优异的长余辉发光材料,是目前有机长余辉发光材料研究的热点。该文从小分子基质体系、大分子基质体系、聚合物基质体系等方面综述了该领域的研究进展,介绍了相关材料在信息加密与防伪、生物成像、柔性纤维薄膜等领域的应用。最后,指出了目前有机掺杂长余辉发光材料在磷光寿命、余辉波长和激发波长等方面的不足,通过对有机材料长余辉发光机理的进一步完善,有望开发出性能更优,应用范围更广泛的纯有机长余辉发光材料。Organic long-persistent luminescent materials,with the advantages of simple preparation,low cost,flexibility and environmental friendliness,have been widely used in the fields of anti-counterfeiting,information security,biological imaging,and other applications.The adjustability of long-persistent luminescent time and color via regulation of the coordination relationship between host and guest in organic long-persistent luminescent materials based on doping system as well as excellent long-persistent luminescent materials synthesized at room temperature have become research hotspot of long-persistent luminescent materials at present.In this review,the research progress in this field was firstly summarized from the aspects of micromolecular matrix system,macromolecular matrix system and polymer matrix system.The applications of relevant materials in information encryption and anti-counterfeiting,biological imaging,flexible fiber film and other fields were then introduced.Finally,the shortcomings,in terms of phosphorescence lifetime,afterglow wavelength and excitation wavelength,were discussed.Organic long-persistent luminescent materials with better performance and broader applications are expected to be developed by further improvement of their luminescent mechanism.
