Flexible electrofluorochromic devices with the highest contrast ratio based on aggregation-enhanced emission (AEE)-active cyanotriphenylamine-based polymers

Flexible electrofluorochromic devices were prepared from two electrochromic and AEE-active (AEE: aggregation-enhanced emission) cyanoarylamine-containing high-performance polymers, exhibiting the highest contrast ratio (I-f/I-f0) of 151.9 at a low working potential.
