摘　　要：以四（对甲基苯基）卟啉锌（ZnTMPP）配合物为核心配体，选择联吡啶、联苯胺和新合成的Schiff碱-双（4-吡啶甲醛）缩联苯胺为桥联配体合成了3种新型π-π共轭的一维线性配位聚合物。通过FT-IR、1H-NMR、UV-Vis NIR和XRD衍射谱图等对配体及配位聚合物结构进行了表征。考察了桥联配体的长度及结构对配位聚合物光学性能、电性能和结晶态的影响。结果表明，以Schiff碱-双（4-吡啶甲醛）缩联苯胺为桥联配体合成的配位聚合物在300~1 100 nm有宽吸收带，并且可在低电位发生氧化还原反应，其满带和空带之间的能隙为0.19 eV；以联吡啶和联苯胺为桥联配体的配位聚合物结晶度较好。Three novel π-π conjugated one dimensional linear coordination polymers, [（ZnTMPP）LBD], [（ZnTMPP）LBA-LBD] and [（ZnTMPP）LBA] were synthesized using Zn（Ⅱ） tera-（4-methylphenyl） porphyrin （ZnTMPP） as axial ligand, and bipyridine, benzidine and Schiff base-4,4-bis（pyridine-2-methyleneamino） biphenyl as bridging ligand, respectively. These coordination polymers were characterized by FT-IR, 1H-NMR, UV-Vis NIR and XRD. The effects of bridging ligand length and structure on the optical, electrochemical properties and crystalline of coordination polymers were investigated. Results showed that the coordination polymer bridged by the longest [（ZnTMPP）LBA-LBD] bridging ligand had broadband adsorption in the range of 300—1 100 nm, and a redox reaction could occur at a lower potential. The energy gap between the full band and the empty band was 0.19 eV. The coordination polymers which bridged by bipyridine and benzidine had semi crystallinity.
