【摘要】 合成了4-[对-(N-正丁基-N-苯基)苯胺基]-2,2′∶6′,2″-三联吡啶钌配合物{[Ru(L)2](PF6)2},利用电化学沉积法在0.1mol/L Bu4NClO4/CH3CN溶液中制备了导电聚[Ru(L)2]2+膜,并用SEM表征了膜的形貌。交流阻抗谱研究表明,聚合物膜的厚度随扫描圈数的增加而增大,光谱电化学方法研究表明聚[Ru(L)2]2+膜处于中性态是红色而在完全氧化态则几乎无色。研究了聚合物膜的电致变色性质,表明聚[Ru(L)2]2+膜是一种具有潜在应用价值的电致变色材料。更多还原

【Abstract】 A functionalized complex [Ru(L)2](PF6)2 {L=4′-[(4-(diphenylamino)phenyl)]-2,2′∶6′,2″-terpyridine}were synthesized.The electrically conductive poly-[Ru(L)2]2+ films were synthesized through electropolymerization on Pt/ITO electrode in a 0.1mol/L Bu4NClO4/CH3CN solution.Morphological characterization of the film on indium tin oxide(ITO) was provided by scan electron microscopy(SEM).The polymer film thickness was easily tuned by controlling the number of potential sweeping cycle,and the AC impedance of as-formed film increased with cycling number.The spectroelectrochemic analysis showed that the poly-[Ru(L)2]2+ film was red in the neutral state and achromaticity(1.7V) in the fully oxidized state.The electrochromic properties of the polymer films were investigated,indicating that poly-[Ru(L)2]2+ film is a potential application valued electrochromic material.更多还原
