摘要：
Two hydrophobic imidazolium based ionic liquids including 1-benzyl-3-butylimidazolium hexafluorophosphate [BzBIM]PF6 and 1-pentyl-3-butylimidazolium hexafluorophosphate [PBIM]PF6 having the same anion and different cation parts were synthesized. The structural composition of these ionic liquids were confirmed with Fourier-transform infrared spectroscopy (FT-IR) and proton nuclear magnetic resonance (H-1-NMR). Their physiochemical properties such as viscosity, ionic conductivity and thermal stability alongside electrochemical potential window range for both ionic liquid electrolytes were characterized and compared to each other. The overall results revealed that [BzBIM]PF6 has higher thermal and electrochemical stabilities and viscosity than that of [PBIM]PF6 probably due to the presence of benzyl ring in the imidazolium cation providing strong intermolecular pi-pi interactions.
