摘　　要：自有机发光二极管(OLED)诞生以来,科学家一直致力于开发高效的发光材料,力求获得更优越的器件性能。近年来,含有氮杂环卡宾(NHC)的金(Ⅰ)配合物,通过搭配合适的给体单元(如酰胺、炔基、芳基),不仅能够展现出超快的辐射衰减速率,还能实现接近100%的发光量子产率,被视为发光材料领域的一颗璀璨新星,展现出广阔的应用前景。系统地综述了氮杂环卡宾金(Ⅰ)配合物发光材料的研究进展,通过剖析不同配体基团的选择策略,结合分子设计原理,探讨分子结构与其光电性能之间的内在关联,并进一步分析这些材料在提升OLED性能方面的潜力与应用前景。Since the advent of organic light-emitting diodes(OLEDs),scientists have been dedicated to developing efficient luminescent materials to achieve superior device performance.In recent years,gold(Ⅰ) complexes containing N-heterocyclic carbenes(NHCs) have emerged as a rising star in the field of thermally activated delayed fluorescence(TADF) materials.When paired with suitable donor units(such as amides,alkynes,and aryls),these complexes can not only exhibit ultrafast radiative decay rates but also achieve nearly 100% photoluminescence quantum yields(PLQYs),showcasing vast application potential.This article systematically reviewed the research progress of gold(Ⅰ) complex luminescent materials containing NHC.By analyzing the selection strategies for different donor groups in conjunction with molecular design principles,we explored the intrinsic relationships between molecular structures and their photophysical properties.Furthermore,we discussed the potentials and application prospects of these materials in enhancing OLED performance.
