| Abstract | 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). |
