摘　　要：利用Mcmurry反应较高效率地合成了具有三苯胺和四苯乙烯骨架的环状聚集诱导发光(AIE)特性化合物,并考察了其光学和电化学性质。所有产物结构均通过(1)^H NMR、(13)^CNMR和元素分析等进行了表征。由于AIE特性和目标化合物的刚性结构,使其显示出423 nm和505 nm双重发射特性。目标产物还表现出较高的热稳定性和玻璃化转变温度,HOMO值(-5.55 eV)和LUMO值(-2.60 eV)表明其适用于空穴传输材料。A new macrocyclic AIE emitter with the backbone of triphenylamine(TPA)and tetraphenylene ethylene(TPE)was synthesized efficiently by Mcmurry reaction.The optical and electrochemical properties of the compound were investigated.All products'structures were characterized by (1)^H NMR,(13)^CNMR and elemental analysis.Due to Aggregation-Induced Emission(AIE)characteristic and the rigid structure of the compound,it showed dual emission characteristics at 423 nm and 505 nm.The compound also had high thermal stability and glass transition temperature.HOMO value(-5.55 eV)and LUMO value(-2.60 eV)showed that it was suitable for hole transport materials.
