Charge transport processes in nonconjugated redox-active polymers with electrolytes were studied using a diffusion-cooperative model. For the first time, we quantitatively rationalized that limited Brownian motion of redox centers bound to resulted 103–4-fold decline bimolecular and heterogeneous charge transfer rate constants, which had been unexplained for half century. As next-generation design, supramolecular system high physical mobility was proposed achieve constant as free solution (>107 M–1 s–1) populated site density (>1 mol/L).
