摘　　要：以4-甲酰基三苯胺和1,10-菲咯啉-5,6-二酮为原料,经过缩合、甲基化等反应合成了配体N-甲基-2-(4-二苯胺基苯基)咪挫并[4,5-f][1,10]-菲咯啉(TPAPhen),再与Fe^(2+)2+配位得到配合物[Fe^(2+)(TPAPhen)3](BF4)2,最后经过电化学聚合在ITO玻璃表面制备了新型电致变色材料poly-Fe^(2+)(TPAPhen)3。在外加电压作用下,poly-Fe^(2+)(TPAPhen)3聚合物薄膜表现出多种颜色变化和良好的电致变色性能,尤其是在721 nm处的光学对比度高达86%,着色效率高达971 cm^(2)·C^(-1),并且表现出较快的响应速度(着色时间:2.6 s,褪色时间:5.3 s)。A Fe^(2+)(Ⅱ) complex [Fe^(2+)(TPAPhen)3](BF4)2 was prepared by coordination reaction between Fe^(2+)2+ ion and the ligand N-(4-(1-methyl-1 H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)phenyl)-N-phenylbenzenamine(TPAPhen),which was synthesized from the starting materials including 4-(diphenylamino)benzaldehyde and 1,10-phenanthroline-5,6-dione through condensation reaction and methylation.Then the electrochromic material poly-Fe^(2+)(TPAPhen)3 was deposited on the ITO glass by electropolymerization of [Fe^(2+)(TPAPhen)3](BF4)2.Poly-Fe^(2+)(TPAPhen)3 exhibited multicolor change and good electrochromic performance under external voltage.Especially,a high optical contrast of86% was achieved at 721 nm with a fast switch speed(coloration time:2.6 s,bleaching time:5.3 s) and high coloration efficiency of 971 cm^(2)·C^(-1).
