摘　　要：基于热活化延迟荧光的双发射有机材料,由于具有两种颜色的发光波长,且至少有一种发射的衰减寿命在微秒级以上,因此在白色有机发光二极管、多功能探针与传感、高质量生物成像、防伪等领域具有很大的应用前景。为了合理地设计基于热活化延迟荧光的双发射有机电子给体-受体型材料,最为关键的是研究分子结构与光物理性质之间的构效关系。本文将基于热活化延迟荧光的双发射有机电子给体-受体型分子,根据其发光属性分为三类:热活化延迟荧光-荧光双发射、热活化延迟荧光-磷光双发射和双热活化延迟荧光发射,进一步对其分子设计原则、发光机制和最新进展做出了简要综述,并展望了其发展前景。The organic thermally activated delayed fluorescence materials with dual-emission characteristics have possessed great application in fields of white organic light emitting diodes,multifunction probes and sensors,high quality bioimagings,anti-counterfeiting and so on,owing to their different wavelengths and at least one long lifetime more than microseconds.Moreover,it is critical to study the structure-property relationships for designing thermally activated delayed fluorescence moleculars with dual-emission based on donor-acceptor system.In this paper,the thermally activated delayed fluorescence materials with dual-emission based on donor-acceptor system are divided into three categories according to their luminescent properties:thermally activated delayed fluorescence-fluorescence dual emission,thermally activated delayed fluorescence-phosphorescent dual emission and dual thermally activated delayed fluorescence emission.The molecular design principle,luminescence mechanism and the progress are reviewed,noting the remaining challenges and directions for future work.
