Electrochromic materials multicolored

Electrochromic materials are cheap and simple to produce and they can provide reasonable contrast for a variety of colors [13], The increasing popularity of electrochromic materials is due to their rapid response times, long lifetimes, high optical contrasts and their ability to be modified in order to create multicolored electrochromics [7],... 

Copolymers of thiophenes and didodecyloxybenzenes have been synthesized as well, exhibiting multicolor electrochromism coupled with high contrast ratios and fast response times (Scheme 8) [45]. Since all three basic colors in the RGB (red-green-blue) system can be obtained, the material is a potential candidate for display applications. 

Fused azole systems with three heteroatoms can be represented by ben-zothiadiazole (BT), benzoselenodiazole (BSe), benzotriazole (BTA)." Among them the heterocycle BT is most widely used in conjugated co-polymers. Derivatives of BT have been widely used in organic electronic devices, especially in terms of electrochromic applications. While incorporated into the conjugated backbone these BT moieties bring to the polymeric material such properties as strong ICT transition dipole, multicolored electrochromism and efficient photoluminescence.
