Abstract
In this study,a series of arylene-bridged bis(benzimidazolium)triflates 1-62+·2[OTf-]were synthesized by grafting different π-linkers with benzimidazolium scaffolds.Among them,compound 12+·2[OTf-]with anthracene as the linker exhibited remarkable electron transfer capabilities across four distinct redox states.The inclusion of an anthracene unit as the π-linker contributes to its exceptional redox and opto-electronic characteristics.Consequently,12+·2[OTf-]was successfully utilized as both an electrochromic molecule in an ECD under applied voltage for the first time,and a highly efficient photocatalyst for the formation of carbon-phosphorus bonds via visible-light-induced cross-dehydrogenative coupling re-actions.
