## Abstract 3,3,4,4‐Tetaaryldihydro[5]helicenes (**1**) and 1,1′‐binaphthyl‐2,2′‐diylbis(diarylcarbenium)s (**2**^2+^) can be reversibly interconverted upon electron transfer, which is accompanied by a vivid color change (electrochromism) as well as by the formation/cleavage of a CC bond (“dynamic
