In this work, novel terpyridine-Fe(Ⅱ) coordination polymers were prepared by introducing an aromatic ring as a π-spacer between two terpyridine units to construct multi-dented ligands, which were coordinated with Iron(Ⅱ) tetrafluoroborate hexahydrate. The electrochromic properties of the terpyridine-Fe(Ⅱ) coordination 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 cm²·C^-1).
