摘　　要：以合成的2,6-双(1-(4-(9H-咔唑-9-基)苯基)-1H-1,2,3-三唑-4-基)吡啶(CPTP)为单体,采用氯仿为溶剂、无水三氯化铁为催化剂,通过氧化偶联方式合成一种共轭微孔聚合物(PCPTP).利用红外光谱、固体核磁碳谱、紫外可见漫反射谱等表征聚合物的结构和性质.实验结果表明,PCPTP具有很强的可见光吸收能力,可以有效催化可见光诱导N-取代四氢异喹啉的α-氧化反应,且可重复回收使用多次.密度泛函理论(DFT)计算结果表明,聚合物的电子供体-受体(DA)结构是PCPTP具有高效光催化性能的重要因素.Using the synthesized 2,6-bis(1-(4-(9H-carbazol-9-yl)phenyl)-1H-1,2,3-triazol-4-yl)-pyridine(CPTP)as monomer,chloroform as solvent and anhydrous ferric chloride as catalyst,a conjugated microporous polymer(PCPTP)was synthesized by oxidative coupling method.The structure and properties of the polymer were characterized by infrared spectroscopy,solid-state ^(13)C NMR spectroscopy,UV-vis diffuse reflectance spectroscopy,etc.The experimental results show that PCPTP has strong visible light absorption ability and can effectively catalyze visible-light induced α-oxidation of N-substituted tetrahydroisoquinolines.Moreover,the catalyst can be recycled and reused for several times without activity loss.The density functional theory(DFT)calculation results suggest that the electron donor-acceptor(D-A)structure of the polymer is an important factor for the efficient photocatalytic performance of PCPTP.
