中文摘要：有机集成化光电子器件兼具了小型化和多功能性的优势,如集成了有机发光和紫外探测的有机发光紫外探测器件(OLED-UVOPDs).这种器件中的有机光电材料的设计仍然面临重大的挑战.在本文中,以蒽为π桥,腈基苯为受体,三苯胺(TPA)和二甲基三苯胺(2mTPA)分别为给体,设计并合成了两种可用于OLED-UVOPD器件的蓝色发光分子,TPA-AN和2mTPA-AN.它们的发光峰分别位于474和488 nm处,荧光量子产率为51.1％和46.6％.通过单载流子器件计算得到其电子迁移率分别为3.96 × 10-5和6.63 × 10-7 cm2 V-1 s-1.基于TPA-AN的OLED器件表现出强的蓝光发射,最大亮度为43,110 cd m-2,最大外量子效率(EQE)为8.1％.它们在OLED-UVOPD集成器件中表现出优异的性能,紫外探测率分别为7.18 × 1011和2.85 × 1012 Jones,最大EQE分别为8.7％和 5.9％.

外文摘要：The design of materials for devices that integrate organic light-emitting diode and ultraviolet organic photo-detectors(OLED-UVOPDs)faces a grand challenge.In this study,we synthesized two blue fluorescent emitters utilizing triphenylamine(TPA)and 4-methyl-N-phenyl-N-(p-tolyl)-aniline(MeTPA)units as donors,benzonitrile as an acceptor,and anthracene(AN)as a bridge,namely TPA-AN and 2mTPA-AN.Notably,both emitters demonstrated high ab-solute fluorescence quantum yields of 51.1％for TPA-AN and 46.6％for 2mTPA-AN with emission peaks at 474 and 488 nm,respectively.Single-carrier devices indicated favorable elec-tron mobilities of 3.96 × 10-5 cm2 V-1 s-1 for TPA-AN and 6.63 × 10-7 cm2 V-1 s-1 for 2mTPA-AN.Furthermore,the OLED based on TPA-AN exhibited a pure blue emission with a brightness of 43,110 cd m-2 and a maximum external quantum efficiency(EQE)of 8.1％.The integrated OLED-UVOPD de-vices based on TPA-AN and 2mTPA-AN,achieved detectiv-ities of 7.18 × 1011 and 2.85 × 1012 Jones,along with EQEs of 8.7％and 5.9％,respectively.
