| Abstract: | The 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)‐ 1 2+ 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. |
