As shown in Table 3, this selectivity coefficient increases with decreasing tubule diameter. The smallest tubule-diameter R ϭ -C 2H 4-OH membrane showed a factor of 23 higher selectivity for pyridine transport than the corresponding R ϭ -C 16H 33 membrane. Similar large α OH/C16 values were obtained for two other relatively hydrophilic organic molecules—benzoic acid (α OH/C16 ϭ 28) and phenol (α OH/C16 ϭ 15). Results of analogous permeation studies for the hydrophobic toluene molecule are shown in Fig.
These membranes can be as permse- * This reported pzc is for polycrystalline Au. Electrochemists may debate the precise meaning of the pzc for a polycrystalline metal surface. However, for our purposes here it is the potential at which there is no net excess charge on the polycrystalline metal surface. † This is undoubtedly because prior studies have shown that, because of its short alkyl chain, PT monolayers are disordered. ‡ Although polymeric membranes that show switchable transport properties have been described, the switchability was based on Faradaic electrolysis of the polymer.
Such anion adsorption can be prevented by chemisorbing a monolayer of a strongly adherent thiol molecule to the Au surfaces [97,98]. † The E m versus applied potential curves for an untreated and PT-treated gold nanotubule membrane, with KBr solutions present on either side of the membrane, are shown in Fig. 13. The untreated membrane shows only cation permselectivity, but the permselectivity of the PT-treated membrane can be switched, exactly as was the case with the nonadsorbing electrolyte (Fig.
