摘　　要：采用改进的“Adler法”,合成meso-四噻吩基卟啉(TTP),采用“两步法”络合钴离子合成了meso-四噻吩基卟啉钴(TTP-Co),收率为61.02%。其结构和性能经红外光谱、紫外及荧光光谱测试。其溶剂化效应结果表明:TTP-Co的发光现象明显减弱,且受基态影响较大。AIE效应结果表明:TTP-Co有AIE现象。pH效应结果表明:不同pH缓冲溶液对TTP-Co的荧光现象几乎没什么影响。循环伏安特性曲线结果表明:TTP-Co的能级差为1.35,能隙较低,具有良好的氧化还原可逆性。Meso-tetra-thienyl porphyrin(TTP)was synthesized by improved Adler method,and meso-tetra-thienyl porphyrin cobalt(TTP-Co)was synthesized by two-step method by complexing cobalt ions,with a yield of 61.02%.Its structure and properties were tested by IR,UV and fluorescence spectra.The results of solvation effect showed that the luminescence of TTP-Co was obviously weakened,and was greatly influenced by the ground state.The result of AIE effect showed that TTP-Co had AIE phenomenon.The results of pH effect showed that different pH buffer solutions had little effect on the fluorescence of TTP-Co.The results of cyclic voltammetric characteristic curve showed that TTP-Co had a low energy gap with an energy level difference of 1.35,and good redox reversibility.
