以咔唑、亚芴基肼等为原料,通过suzuki反应合成了2个新型咔唑衍生物：N-乙基-3,6-双(亚芴基肼基-5-亚甲基-2-噻吩)咔唑(S1)和N-(亚芴基肼基-4-亚甲基苯基)-3,6-双(亚芴基肼基-5-亚甲基-2-噻吩)咔唑(S2)。用FTIR、1HNMR、元素分析对S1和S2的结构进行表征,并考察其紫外吸收光谱、荧光光谱、电化学行为和热稳定性。结果表明：S1和S2薄膜的最大发射波长分别在637和649nm处,均发射红色荧光,且S1和S2均具有良好的聚集诱导发光(AIE)特性；S1和S2的HOMO能级分别是-5．26和-5．29eV,与正电极(ITO)的功函数(-4．8 eV)相匹配,可有效降低空穴注入能垒,有利于空穴的传输；S1和S2的热分解温度分别是351和360℃,均具有良好的热稳定性。

Two novel carbazole derivatives(S1 and S2)were synthesized with carbazole and fluorenone as raw materials via Suzuki coupling reactions. The structures of the S1 and S2 were characterized by means of FTIR,1 H NMR and elemental analysis. Their UV-Vis spectra,fluorescence spectra,electrochemical behavior and thermal stability were studied respectively. The results showed that the thin films of the S1 and S2 emited red fluorescence at 637 and 649nm,respectively. They both had the obvious performance of aggregation induced emission(AIE). The HOMO energy levels of S1 and S2 were-5. 26 and-5. 29 eV,which matched with work function(-4. 8 eV) of positive electrode ITO,so the barrier of hole transporting could be effectively reduced and beneficial for hole-transport. The results of TG curves showed that their thermal decomposition temperatures( Td) are 351 and 360℃,respectively,and they both had good thermal stability.
