合成了一种新型的基于吩噻咪唑的深蓝色发射体PhImPOTD,将其与给电子二苯并噻吩单元,吸电子菲并咪唑和二苯基膦氧化物部分结合。此外,弱的π-π堆积和分子间聚集使固态的光致发光量子产率高达0.34。基于PhImPOTD发射器的非掺杂有机发光二极管(OLED)表现出3.6 V的低导通电压,1.13 cd A -1的有利效率以及国际照明委员会(CIE)坐标的深蓝色发射(0.15,0.08)。CIE非常接近NTSC(国家电视标准委员会)蓝色标准(CIE:0.14、0.08)。飞镖还用作蓝光发射器,并用作黄光发射器(PO-01)的主体,以制造白色有机发光二极管(WOLED)。在1000 cd m -2的亮度下,前视最大CE为4.83 cd A -1,CIE坐标为(0.32,0.32)。而且,单载波设备清楚地证明了PhImPOTD的典型双极主导特性。这项工作不仅证明了菲并咪唑单元是构建深蓝色发射材料

Transition‐metal‐catalyzed coupling reactions are useful tools for synthesizing aryl sulfur compounds. However, conventional transition‐metal‐catalyzed thiolation of aryl bromides and chlorides typically requires the use of strong base under elevated reaction temperature. Herein, we report the first examples of nickel‐catalyzed electrochemical thiolation of aryl bromides and chlorides in the absence
