Abstract

Conductive inorganic-organic hybrid monomers and polymers were successfully obtained by using a polymerizable imidazolium ionic-liquid with a methacryloyl group (denoted as MAImC₁) and inorganic polyoxometalate cluster anion ([SiW₁₂O₄₀]⁴⁻, SiW₁₂). The MAImC₁-SiW₁₂ hybrid monomer was synthesized as single crystals, the molecular and crystal structures of which were revealed by single crystal X-ray analysis. The obtained MAImC₁-SiW₁₂ hybrid monomer was found to be polymerized by a radical polymerization using AIBN as an initiator to form inorganic-organic homo- and copolymers. The hybrid copolymers of MAImC₁-SiW₁₂ polymerized with another polymerizable ionic-liquid (denoted as MAImC₈) exhibited high conductivity of 10⁻³ S cm⁻¹ order under humidified condition at near room temperature of 313 K.
