摘　　要：将芳环作为桥联基团引入到2个三联吡啶单元之间构建多齿配体,与四氟硼酸亚铁六水合物配位,制备了一类新型的三联吡啶铁配位聚合物,并研究了其在水系电解液中的电致变色性能。研究结果表明,芳环上氟原子的引入对材料电致变色性能具有一定的影响。其中,采用含有2个氟原子的配体F2制备的铁配位聚合物Fe-F2表现出优异的电致变色性能(光学对比度高达69%,响应时间短至0.5 s,着色效率超过320 cm^(2)·C^(-1))。In this work,novel terpyridine-Fe(Ⅱ)coordination polymers were prepared by introducing an aromatic ring as aπ-spacer between two terpyridine units to construct multi-dented ligands,which were coordinated with Iron-tetrafluoroborate hexahydrate.The electrochromic properties of the terpyridine-Fecoordination polymers were investigated.The results indicated that the introduction of fluorine atoms on the aromatic ring had a certain effect on their electrochromic properties.Among them,coordination polymer Fe-F2 prepared derived from the ligand F2 containing two fluorine atoms showed excellent electrochromic properties(optical contrast up to 69%,response time as short as 0.5 s,coloration efficiency over 320 cm^(2)·C^(-1)).
