A method of making a photoreceptor charge transport layer involves the steps of applying at least one macrocyclic carbonate oligomer to a supporting surface, and in situ polymerizing the at least one macrocyclic oligomer to form at least one high molecular weight polymer; the at least one macrocyclic oligomer being a cocyclic or ter-cyclic oligomer comprising bisphenol glycol bischloroformate moieties and dihydroxy arylamine moieties.
