摘要：

Electrochromic symmetric and non-symmetric disubstituted oxo-bipyridinium ionic liquids are developed in high purities and yields. Detailed spectroscopic (NMR, FTIR and elemental analysis), thermal (DSC for melting point and glass transition temperatures, T-g determination) and electrochemical (cyclic and square wave voltammetry for determination of redox potential and evaluation of reversibility behaviour) analyses are performed. The most promising electrochromic oxo-bipyridinium ionic liquids in combination with transparent electrolytes are tested as reversible electrochromic devices. More efficient and sustainable electrochromic devices inspired by bipyridinium ionic liquids can be conceived for industrial applications such as electrochromic car rear-view mirrors and smart windows.
