摘要/Abstract

以硅杂吖啶(DPDBA)和咔唑衍生物作为电子给体、苯甲酮作为电子受体构筑给体-受体-给体(D-A-D')型分子, 开发了三个蓝光材料. 对材料的热稳定性、电化学性质、单晶结构、光物理性质和电致发光性能等进行了系统研究. 三个材料具有较小的单线态-三线态能级差以及微秒级别的延迟荧光寿命, 并表现出显著的聚集诱导延迟荧光(AIDF)特性. 以这些材料作为发光层制备的有机发光二极管(OLED)的最大外量子效率(EQE)达到14.8%, 发光峰在474~476 nm. 由于这些AIDF分子具有良好的双极载流子传输性能, 将这些材料作为主体材料制备了不同光色的磷光OLED器件, 器件表现出较为优秀的性能, 其中黄光和绿光器件的EQE分别为25.5%和21.2%, 在1000 cd•m⁻²亮度下效率滚降非常小. 因此, 所制备的这些AIDF分子可分别作为发光材料和主体材料用于高性能OLED器件的制备, 具有较好的应用前景.

Three blue-emitting materials were developed using 10,10-diphenyl-5,10-dihydrodibenzo[b,e][1,4]azasiline (DPDBA) and carbazole derivative as donors, and benzophenone as acceptor to construct donor-acceptor-donor (D-A-D') type molecules, and their thermal stability, electrochemical properties, single crystal structure, photophysical properties and electroluminescence properties were systematically studied. And they have small singlet-triplet energy splitting and microsecond- scale delayed lifetimes, showing obvious aggregation-induced delayed fluorescence (AIDF) characteristics. As light-emitting layers of organic light-emitting diodes (OLEDs), the electroluminescence peaks of these compounds are in the range of 474~ 476 nm, and the maximum external quantum efficiency (EQE) can reach 14.8%. Additionally, these compounds exhibit good bipolar carrier transport performance, and can be used as host materials for phosphorescent devices. The maximum EQEs of green and yellow phosphorescent OLEDs are 25.5% and 21.2%, respectively, and the efficiency roll-off at 1000 cd•m^－2 is very small. These results indicate that these AIDF compounds can be used not only as luminescent materials but also as host materials for the preparation of high-performance

Key words: organic light-emitting diode (OLED), aggregation-induced delayed fluorescence (AIDF), host material, aggregation-induced emission
