摘要

有机发光二极管（Organic light‑emitting diodes，OLEDs）经过30余年的发展，在显示和照明领域已经进入了大规模应用的阶段。有机红光及绿光OLEDs基本上已能够达到商业应用的标准，但是蓝光OLEDs仍然存在亮度低、高亮度下寿命短的问题，因而商业上对兼具高激子利用率及高稳定性的蓝光材料和器件的需求显得尤为迫切。为了解决这一问题，国内和国际上相继提出了基于重金属配位的磷光配合物、三线态‐三线态湮灭、热活化延迟荧光、“热激子”等材料结构的设计策略，期望在获得高发光量子效率和激子利用率的同时，尽量减小器件的效率滚降，获得具有高稳定性、长寿命的蓝光OLEDs器件。本文总结了不同类型蓝光OLEDs材料的研究进展，并对未来蓝光材料的发展趋势进行了展望。

Abstract

Organic light-emitting diodes have been widely used in display and lighting fields after more than 30 years of development. Red and green emitting OLEDs have basically been able to meet the commercial requirements， but blue-emitting OLEDs still have the defect of low brightness and short operation lifetime at high brightness. Therefore， the commercial is dying to blue-emitting materials with high exciton utilization efficiency（EUE） and high device stability. Design strategies for material such as heavy-metal phosphorescent complexes， triplet-triplet annihilation （TTA）， thermally activated delayed fluorescent （TADF） and “hot exciton” have been proposed so as to meet the demands of industrial standards. It is expected to obtain blue-emitting OLEDs device with high stability and long lifetime while achieving high photoluminescence quantum yield （PLQY） and the exciton utilization efficiency as well as reduce the efficiency roll-off of devices whenever possible. This paper summarizes the recent progress of different material structure design schemes and prospects the development trends of blue-emitting OLEDs materials.
