The incorporation of F atoms endows a diethenylbiphenyl‐based electron donor with configurational stability and S N Ar reactivity. The former enables the dynamic redox pair of ( R ax )‐ 1 /( R ax , R , R )‐ 1 2+ to exhibit drastic UV/Vis and CD spectral changes upon electrolysis, whereas the latter makes it possible for ( R ax )‐ 1 to serve as a useful chiral synthon for the production of larger assemblies [( R ax , R ax )‐ 2 d,p,m and ( R ax , R ax , R ax )‐ 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.
