摘要

1-Alkyl-4-vinylpyridinium ions (A4VP,1) are potentially important precursors topoly(1-alkyl-4-vinylpyridiniums) (PA4VP, 2). PA4VP are well-known, versatile polymeric materials. They have been widely studied and have found use as polyelectrolytes, surfactants, enzyme mimics, and immobilization media for biomolecules and electroactive assemblies. Synthesis has usually been accomplished by alkylation of poly(4-vinylpyridine). This convenient method only becomes limiting when complete alkylation of pyridine residues or introduction of two or more different N-alkyl groups becomes an issue. In these cases, polymerization of either one kind of monomer or mixtures of monomers with different alkyl groups, assures formation of completely alkylated species with single or multiple alkyl groups as desired.
