In this work, complexes of Zr(IV) and Al(III) cations with tert-butyl substituted tetraphenylporphyrin or tetraazaporphine were tested as F--selective ionophores in plasticized aminated or carboxylated PVC membranes of ion-selective electrodes. It was found that functional groups present in the backbone of applied polymers influence the complexing properties of tested ligands, causing changes of F--selectivity of electrodes prepared with their use in comparison with the electrodes with unmodified PVC membranes. This work shows, that application of functionalized PVC can eliminate the need of relatively expensive ionic sites addition to ion-selective membranes doped with metallocomplexes.
