A biscyclometalated rutheniumcomplexbridged by the 2,7-deprotonated form of 1,3,6,8-tetra(2-pyridyl)pyrene was deposited onto indium–tin oxide glass electrodes by reductive electropolymerization. The resulting metallopolymeric films exhibited tricolor electrochromic behavior in the near-infrared region upon switching of the two well-separated RuII/III processes at low potentials. A good contrast
通过还原电聚合,将由2,7-去质子化的1,3,6,8-四(2-吡啶基))桥接的双环金属化钌络合物沉积在氧化铟锡玻璃电极上。当在低电势下切换两个良好分离的Ru II / III过程时,所得的金属聚合物膜在近红外区域显示三色电致变色行为。对于这种电致变色行为,记录了在2050 nm处的良好对比度(35%)和长达100分钟的长存储时间。响应时间通常为几秒钟。
