碩士 === 國立中央大學 === 化學研究所 === 95 === Reported in the manuscript is the synthesis of diimidazolium-based ionic liquids and N-alkyl imidazoliums immobilized on POSS (polyhedral oligomeric silsesquioxane). The latter consists of eight propyl alley imidazolium chloride functional groups extending from the cubic silsesquioxane core. There POSS immobilized ionic liquids have been analyzed with transmission electron microscope and particle size analyzer. There the nanocomposites shown obvious aggregation.Diimidazolium-based ionic liquids and POSS immobilized ionic liquids have been tested for usage in electrolyte for DSSC (dye-sensitized solar cellxed with methanol). The high viscosity of POSS immobilized ionic liquids in electrolyte reduces the efficiency of cells. The mixture of POSS immobilized ionic liquids (with terminal N-butyl imidazoliums) and methanol was precipitated on ethyl acetate. The POSS immobilized ionic liquids forms bubbles filled with methanol vapors upon supersonic agitation and the bubbles arise to the top surface of the ethyl acetate when the POSS immobilized ionic liquids contanting enclose the methanol vapers.
