<p>Cation complexes that comprise a cation guest and a polydentate polymeric host. The host contains 2,5-diyl, 2,6-diyl, or combinations of 2,5- and 2,6-diyl units to provide specified arrays of hereto atoms. Complexes of the invention employ the above-mentioned host thereby overcoming the need to utilize different host materials for different cation guests. The complexes of the invention are stable. Complexes of the invention are useful in rendering cation-containing salts soluble in organic solvents; enhancing the reactivity of cation-containing salts in nucleophilic substitution reactions; modifying solid surfaces to render them more organophilic; and forming stable suspension and dispersions of particulate solids in organic solvents. </p> |
