The microelectrode solid-state voltammetrically measured, center-of-mass self-diffusion coefficient for Fc-MePEG in its polymer melt, I .3 X cm2/s at 62 OC, is 3.4 times smaller than that for ferrocene monomer dissolved in unlabeled (MW = 2380) MqPEG. Electron hopping is estimated to contribute less than 10% to the diffusion rates of Fc-MePEG and of monomer dissolved at 40-50 mM concentrations in unlabeled Me2PEG. At room temperature, where Fc-MePEG and Me2PEG are waxy solids, DFs-McPEG is 3.9 X cm2/s, 12 times smaller than that of monomer ferrocene, in Me2PEG, and which corresponds to a diffusion pathlength of ca. 110-200 nm during the electrochemical experiment. Dissolved in CH$N or CH2C12, Fc-MePEG diffuses 8-10 times more slowly than ferrocene monomer which is consistent with transport as a random coiled sphere. This paper describes the voltammetric determination of the center-of-mass self-diffusion coefficient of a linear Dolvmer chain bearing a single redox end group (ferrocene), in the pure polymer phase. and as a Dolvmer solution in unlabeled Dolvmer of similar. .
