摘要金属配合物发光材料凭借其高效的单重态与三重态激子利用能力,已成为有机发光二极管(OLED)器件性能提升不可或缺的核心元素,备受学术界与产业界的青睐。目前,基于铱(Ⅲ)和铂(Ⅱ)的磷光配合物在OLED中已得到广泛应用,但这两类金属的稀缺性在一定程度上限制了有机显示产业的可持续发展。在此背景下,具有显著自旋-轨道耦合效应的金(Ⅲ)配合物发光材料,通过灵活的配体设计策略,能够展现出磷光或热活化延迟荧光(TADF)的发光特性,为高效OLED的发展开辟了新途径。通过优化分子结构和器件制备工艺,金(Ⅲ)配合物发光材料已展现出优异的发光性能和良好的器件稳定性。本文综述了金(Ⅲ)配合物发光材料的研究进展,围绕磷光与TADF两种发光机制,深入剖析了金(Ⅲ)配合物的分子结构与发光性能的内在联系,并展望了其未来发展方向,可为相关领域的研究人员提供有价值的参考。

Abstract: Organometallic complexes have emerged as indispensable core elements for enhancing the performance of OLED devices, due to their ability to utilize singlet and triplet excitons. They have garnered significant attention from both the academic and industrial communities. Currently, phosphorescent complexes based on iridium(Ⅲ) and platinum(Ⅱ) have found widespread application in OLEDs, but the scarcity of these metals limits the sustainable development of the organic display industry. In this context, gold(Ⅲ) complexes, with high spin-orbit coupling constants and flexible ligand design, which can exhibit both phosphorescence and thermally activated delayed fluorescence (TADF) emission, present vast application prospects in the field of high-efficiency OLEDs. Through optimization of molecular structure and device fabrication, gold(Ⅲ) complexes have demonstrated outstanding luminescence performance and device stability. This review summarizes the research progress on gold(Ⅲ) complexes as OLED emitters, analyzing the intrinsic relationship between molecular structure and luminescence properties from both the phosphorescence and TADF perspectives. It also provides an outlook on the future development directions, aiming to serve as a valuable reference for researchers in this field.

Key words: gold(Ⅲ) complex phosphorescence TADF organic light-emitting diodes luminescent material
