Abstract: Compound containing at least 15% inorganic content demonstrates liquid-like behavior and is distinct in exhibiting liquid-like behavior in the absence of solvent. In one case it is quaternary ammonium derivative of a heteropolyacid. In another case, it is a salt formed by reaction of heteropolyacid and polyethylene glycol alkylamine. In other cases, it is condensation product of oxide and quaternary ammonium cation where the balancing anion has a molecular weight greater than 200. In still other cases it is a salt formed by reaction of sulfonated silica or sulfonated fullerene and polyethylene glycol alkylamine. In still other cases, it is a neutral organic-inorganic hybrid which is PEG-functionalized silica nanoparticle or is a layered-nanoparticle obtained by hydrolytic polymerization of organosilane in nonpolar solvent.
