Abstract Ionic liquids (ILs) are organic electrolytes with low melting points, high density, high electrical conductivity, high polarity, chemical and thermal stability. Polymeric ionic liquids (PILs) are prepared by free-radical polymerization process. Ionic liquid monomer is 1-vinyl,3-alkylimidazolium iodide. Using azonisisobutyronitrile (AIBN) as a radical initiator, poly(1-vinyl,3-alkylimidazolium) Iodide is synthesized by free-radical polymerization of ionic liquid monomers. Poly(1-vinyl,3-alkylimidazolium iodide) has a narrow solubility, limited to water or alcohol only. Poly(1-vinyl,3-alkylimidazolium bis(trimethanesulfonyl)imide which prepared by anionic exchange of bis(trimethanesulfonyl)imide (⁻NTf2) for iodide (I⁻) become soluble in less polar solvent, such as tetrahydrofurane. By deprotonating polymeric ionic liquids (PILs), poly(N-heterocyclic carbene)s, denoted poly(NHC)s can be generated. Further reaction to synthesize the zwitterionic adduct by introducing lewis acid would be discussed.
