摘要
Novel one-pot synthesis of layered organoammonium-tetratitanate intercalation compounds by the ion exchange reactions between potassium tetratitanate (K2Ti4O9. nH(2)O) and alkylammonium chlorides in the presence of a crown ether (18-crown-6) or a cryptand ([2.2.2]cryptand) in an organic solvent (1,4-dioxane) is reported. The intercalated alkylammonium ions take a paraffin type arrangement in the interlayer space of tetratitanate. The macrocyclic ligands preferentially interact with interlayer potassium ions to promote the ion exchange reactions. The novel one-pot synthesis of the organic-tetratitanate intercalation compounds is a versatile technique for the preparation of inorganic-organic inclusion complexes.
