The influence of ionophore structure and membrane composition (amount of incorporated ionic sites) on the electrode response, selectivity and long\u2010term stability were studied. Poly(vinyl chloride) polymeric membranes plasticized with <jats:italic>o<\/jats:italic>\u2010NPOE (<jats:italic>o<\/jats:italic>\u2010nitrophenyloctylether) and containing Sn(IV)\u2010tetraphenylporphyrin (TPP) dichloride (Sn(IV)[TPP]Cl<jats:sub>2<\/jats:sub>) or Sn(IV)\u2010octaethylporphyrin (OEP) dichloride (Sn(IV)[OEP]Cl<jats:sub>2<\/jats:sub>), and in some cases incorporating lipophilic cationic (tetraocthylammonium bromide \u2010 TOABr) and anionic (sodium tetraphenylborate \u2013 NaTPB and potassium tetrakis[3,5\u2010bis(trifluoromethyl)phenyl]borate\u2010KTFPB) additives, were prepared and their potentiometric characteristics compared. Both ionophores are shown to operate via a neutral mechanism, and the addition of 10\u2005mol % of lipophilic quaternary ammonium salt derivative to the membrane is required to achieve optimal electrode performance. The potentiometric units prepared, with Sn(IV)[TPP]Cl<jats:sub>2<\/jats:sub> (Type A) or Sn(IV)[OEP]Cl<jats:sub>2<\/jats:sub> (Type B) without additives, presented a slope of \u221252.8\u2005mV dec<jats:sup>\u22121<\/jats:sup> and \u221258.8\u2005mV dec<jats:sup>\u22121<\/jats:sup> and LLLR of 9.9\u00d710<jats:sup>\u22125<\/jats:sup>\u2005mol L<jats:sup>\u22121<\/jats:sup> and 9.9\u00d710<jats:sup>\u22126<\/jats:sup>\u2005mol L<jats:sup>\u22121<\/jats:sup>, respectively. The units prepared using the same metalloporphyrins and incorporating 10% mol TOABr presented a slope of \u221255.0\u2005mV dec<jats:sup>\u22121<\/jats:sup> and \u221257.8\u2005mV dec<jats:sup>\u22121<\/jats:sup> and LLLR of 5.0\u00d710<jats:sup>\u22127<\/jats:sup>\u2005mol L<jats:sup>\u22121<\/jats:sup> and 3.0\u00d710<jats:sup>\u22127<\/jats:sup>\u2005mol L<jats:sup>\u22121<\/jats:sup>.
