✦ Synopsis

Zero-current counter-transport studies as well as electrodialytic transport experiments on solvent polymeric membranes doped with ionophores for anions have been carried out and were compared with potentiometric measurements on the same membranes. A theoretical description of the observed phenomena corroborates that lipophilic complexes of Co(II1) (e.g. aquacyano[heptakis(2-phenylethyl)]Co(III) cobyrinate perchlorate) and Mn(II1) (e.g. lipophilic Mn(II1)porphyrin complexes) act as positively charged carriers for anions, whereas a lipophilic Ru(I1)porphyrin complex has to be described as an electrically neutral carrier for anions.

## Abstract Tin(IV) porphyrins derivatives were used as ionophores for phthalate selective electrodes preparation. The influence of ionophore structure and membrane composition (amount of incorporated ionic sites) on the electrode response, selectivity and long‐term stability were studied. Poly(vin
