英文摘要a method of utilizing p-pi conjugation effects for obtaining low-viscosity ionic liquids is presented. p-pi conjugation effectively disperses anionic charge and reduces coulombic interactions. ionic liquids prepared in this study were 1-ethyl-3-methylimidazolium benzoate (emib) and 1-ethyl-3-methylimidazolium isonicotinate (emiin). they have carboxyl and aromatic ring p-pi conjugated anions, and achieve low viscosities of 42 and 27 mpa . s, respectively. emib and emiin were employed as electrolytes, which were used to construct dye-sensitized solar cells (dscs). after optimizing the composition, the ionic conductivity and triiodide ionic diffusion constant for the emib-based electrolyte were 1.43 ms . cm(-1) and 1.45 x 10(-7) cm(2) . s(-1), respectively. for the emiin-based electrolyte, the ionic conductivity and triiodide ionic diffusion constant were 1.63 ms . cm(-1) and 2.01x10(-7) cm(2) . s(-1), respectively. these were higher than the corresponding values for the emib-based electrolyte because of emiin's lower viscosity. dscs based on these two electrolytes attained satisfactory energy conversion efficiencies of 2.85% and 4.30% for emib and emiin, respectively, under an illumination intensity of 300 w . m(-2).
