摘要
本文合成了一种多齿配体化合物——1,4-双(2,2′:6′,2′′-三联吡啶-4′-基)苯及其Fe/Ru金属-超分子聚合物——Poly Fe和Poly Ru,同时以喷涂在ITO导电玻璃上的Fe/Ru金属-超分子聚合物膜为工作电极、0.1 mol/L Li Cl O4水溶液为电解质,并添加K_3Fe(CN)_6为电化学互补材料,制作了系列电致变色器件.由Poly Fe和Poly Ru的组合,可以得到从Poly Fe的蓝紫色渐变到Poly Ru橙红色的彩色薄膜及其多色电致变色器件,器件响应速度快(<2 s),褪色电压0.9~1.2 V,着色电压0 V,最大光学对比度约57%.添加K_3Fe(CN)_6后,器件的寿命得到极大提高.
A multidentate ligand compound 1,4-bis(2,2':6',2"-terpyridine-4-yl) benzene and its Fe/Ru metallo- supramolecular polymers, PolyFe and PolyRu, were synthesized by a simplified procedure with improved product yield. The Fe/Ru-based metallo-supramolecular polymer films prepared by spray-coating the polymer solution on ITO glasses were used as the working electrode to fabricate electrochromic devices composed of K3Fe(CN)6 as complementary material in the 0.1 mol/L LiC104 aqueous electrolyte solution. By combining PolyFe and PolyRu a series of multicolored films and their electrochromic devices were prepared. These devices exhibited fast response time (〈2 s) with bleaching and coloring voltage of 0.9-1.2 V and 0 V, respectively, and high contrast about 57%. The cycling life of the devices was increased greatly by addition of the complementary material K3Fe(CN)6 in the electrolyte solution.
