Vis-to-NIR electrochromism and bright-to-dark electrofluorochromism in a triazine and thiophene-based three-dimensional covalent polymer

Two triazine and substituted thiophene-based donor–acceptor covalent polymeric frameworks are developed to exhibit the Vis-to-NIR electrochromism and bluish-green-to-quenched electrofluorochromism, simultaneously in a +1.8 to −0.9 V potential range.
