Electrochromism of a bipolar reversible redox-active ferrocene-viologen linked ionic liquid.
A ferrocene-viologen linked "bipolar" type redox-active ionic liquid ([FcC11VC1][TFSI]2) was synthesized as an electrochromic (EC) material that functions without any other additives: solvents, supporting electrolytes and sacrificial agents. The efficiency of a prototype symmetrical EC cell was 70 cm2C-1at 1.0 V. The EC process was stable even after over 10 000 potential cycles.
