title: Assembly of an Axially Chiral Dynamic Redox System with a Perfluorobiphenyl Skeleton into Dumbbell- or Tripod-type Electron Donors.
abstract: The incorporation of F atoms endows a diethenylbiphenyl-based electron donor with configurational stability and SN Ar 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.
