The mol. sieving behavior of soft-etched polyimide membranes having neg. charged nanochannels is described exptl. and theor. using alkali metal-crown ether cationic complexes and alkylammonium cations. To this end, the elec. conduction and current rectification obtained with different alkali electrolyte solutions (LiCl, NaCl, and KCl) and crown ether mols. (12-crown-4, 15-crown-5, and 18-crown-6) are studied. The results suggest that only the [Li(12C4)]+ complex can readily permeate through the nanochannels because significant current decreases are obtained in the cases of the [Na(15C5)]+ and [K(18C6)]+ complexes. In solutions of organic cations ranging from ammonium (NH4+) to alkylammonium (R4N+) with increasing mol. size, only the smaller ions can conduct high elec. currents, suggesting again that the membrane channels are in the nanometer range. Taken together, the observed current decreases and rectification phenomena demonstrate that the functionalized membranes allow a versatile combination of mol. and electrostatic sieving. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Name: Tetramethylammonium chloride).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Name: Tetramethylammonium chloride
