Flexible electrofluorochromic devices with the highest contrast ratio based on aggregation-enhanced emission (AEE)-active cyanotriphenylamine-based polymers†
Abstract
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 (If/If0) of 151.9 at a low working potential.
