Novel chemical pathways and charge-transport dynamics of electrodes modified with electropolymerized layers of [Co(v-terpy)2]2+ (original) (raw)

Electropolymerized films of [Co(~-terpy)~]*' (v-terpy is 4'-vinyl-2,2':6',2''-terpyridinyl) exhibit reactivity patterns, especially with regard to ligand exchange, that differ significantly from those exhibited by [ C~(t e r p y)~]~+ in solution. These differences are attributed to the physically constrained environment present in the polymer f h. The charge-transport properties follow the model of Dahms and Ruff and the predicted concentration dependence of the diffusion coefficient. These electropolymerized films are also active in the electrocatalytic reduction of carbon dioxide.
