Abstract: A Cu2+-ion selective resin was synthesized by a template polymerization technique using oleic acid as a host surfactant and divinylbenzene as a matrix-forming monomer. Acid-dissociation and complexation equilibria of both Cu2+-ion templated and non-templated resins were studied potentiometrically by the use of a glass electrode and a Cu2+ ion-selective electrode. These equilibria are highly sensitive to the added salt concentration levels together with the degree of dissociation of the resin which arises from the polyelectrolyte nature of the carboxylated resins. By correction for electrostatic non-ideality, the microscopic information on the complexation of the resins has been extracted and the intrinsic imprinting effect has been evaluated. The origin of the imprinting effect will be discussed by comparison of the complexation behavior of these two-dimensional polyelectrolytes with a linear (one-dimensional) polyelectrolyte
