Facile Fabrication of Triphenylamine-Based Redox-Active Nanocomposites by a Sol-Gel Method: Enhanced Electrochromic Response Capability and Stability Performance.

摘要: In this research, a new design of organic-inorganic hybrid networks involving covalently bonding, novel, electron-donating triphenylamine (TPA)-containing electroactive molecules to inorganic metal oxides is successfully developed by using facile sol-gel process. These anodically electrochromic TPA-containing materials exhibit multicolor behaviors at various oxidation states. By introducing zirconium oxide into materials, not only can an excellent optical transparency in the visible light region neutral state be achieved given nature large energy bandgap, but switching also driven lower potential with enhanced response capability (shorter coloring times and bleaching times). Moreover, films show outstanding electrochemical stability high reversibility under long-term operations owing their good adhesion electrode. Consequently, devices derived from these novel reveal huge for applications.
