Abstract

AbstractThe incorporation of F atoms endows a diethenylbiphenyl‐based electron donor with configurational stability and SNAr reactivity. The former enables the dynamic redox pair of (Rax)‐1/(Rax,R,R)‐12+ to exhibit drastic UV/Vis and CD spectral changes upon electrolysis, whereas the latter makes it possible for (Rax)‐1 to serve as a useful chiral synthon for the production of larger assemblies [(Rax,Rax)‐2 d,p,m and (Rax,Rax,Rax)‐3] containing two or three dyrex units. These dyads and triad also exhibit a clean electrochiroptical response with isosbestic points owing to one‐wave multi‐electron transfer.
