摘　　要：以硅杂吖啶为给体基团,经格氏偶联、Suzuki偶联和Buchwald-Hartwig偶联合成了一种热活化延迟荧光材料5-(4-(4,6-二苯基-1,3,5-三嗪基)苯基)-10,10-二苯基-5,10-二氢硅杂吖啶(DTPDDA)。优化了合成工艺,并对其结构、热稳定性、光学性能进行表征。结果表明,DTPDDA热分解温度378.93℃,玻璃化转变温度320.75℃,具有较高的热稳定性;同时,DTPDDA具有强发光性能,λmax为456nm,是一种蓝光TADF材料。A thermally activated delayed fluorescent material 5-(4-(4,6-diphenyl-1,3,5-triazin-2-yl)phenyl)-10,10-diphenyl-5,10-dihy-drodibenzo[1,4]azasiline(DTPDDA)based on the donor groups of dihydrophenazasiline,has been synthesized via Grignard coupling,Suzuki-Miyaura cross coupling and Buchwald-Hartwig cross coupling.The synthesis of target compound is optimized to get high yield,and its structure,thermal sta-bility,optical properties are characterized.The results indicate that the DTPDDA has a high thermal stability with a thermal decomposition tempera-ture of 378.93℃and a glass transition temperature of 320.75℃.In addition,the DTPDDA has strong luminescence properties with theλmaxof 456nm,which is a blue TADF material.
