Highly stable viologens-based electrochromic devices with low operational voltages utilizing polymeric ionic liquids

In this work, we proposed an effective route of introducing poly(ionic liquid) (PIL) gel as electrolyte to suppress dimer formation of viologen radical cation during switching in electrochromic devices (ECDs). The ECDs were fabricated based on ion gels consisting of various viologens, PIL and ferrocene (Fc). We found that incorporation of PIL contributed to the suppression of dimer production. The suppression of dimer formation can provide ECDs with improved colouration efficiencies, faster switching times, longer cycle lives, and potentially reduced costs. The results showed that an excellent cyclic stability over 96% of initial transmittance change after 4000 cycles of switching.

The Synthesis and Electrochemical Study of New Electrochromic Viologen-based Materials

A range of diquaternary salts of 4,4'-bipyridine and 3,8-phenanthroline were prepared and subsequently screened using electrochemical and spectroscopic techniques.It was determined that the stability of the radical film deposited on cathodic reduction of aqueous solutions of these salts may be strongly influenced by symmetry, steric, and electronic factors.From this basis, it was possible to design a viologen, 1,1'-bis-(2-methylbenzyl)-2-methyl-4,4'-bipyridinium dibromide (9), having electrochromic properties for electronic display applications superior to those already in existence.A radical film of mixed composition was found to be less susceptible to ageing effects than films generated from the individual dicationic salts.
