| Abstract;Investigations on the potentiometric selectivities of calix[6]arene hexaesters and related hosts revealed that a high dopamine selectivity could be attained by the tri-O-butyl and tri-O-acetic acid ester derivatives of hexahomotrioxacalix[3]arene incorporated in PVC liquid membranes. In addition to structural studies by 1H-NMR and calculation (Hartree-Fock/3-21G*), investigations to understand the reason of potentiometric selectivities were carried out by separating the lipophilicity and complexation factors. It was found that the high dopamine/K+ ion selectivity stemmed from highly selective complexation of dopamine by the host. (author abst.) |
