Pyrrolidinium Overview
Pyrrolidinium-based ionic liquids are non-aromatic, quaternary ammonium compounds with a five-membered ring, valued for their thermal and electrochemical stability. Unlike imidazolium-based counterparts, they lack a protonation-prone carbon, reducing carbene formation and enhancing stability in battery applications (Yamamura et al., 2012). Their robust structure minimizes unwanted side reactions, making them ideal for high-performance electrolytes. Pyrrolidinium salts also exhibit antimicrobial properties, showing potential in pharmaceutical and bioactive material development.
• Thermodynamic Properties
Yamamura et al. (2012) compared N-butyl-N-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide ([bmp][Tf₂N]) with 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide ([bmim][Tf₂N]) using adiabatic calorimetry and DFT-based vibrational analyses. [bmp][Tf₂N] has a lower melting point (265.82 K vs. 270.42 K) due to weaker intermolecular interactions, driven by steric hindrance from methyl and butyl groups, resulting in lower enthalpy (21.9 kJ mol⁻¹ vs. 23.8 kJ mol⁻¹) and entropy (82.4 J K⁻¹ mol⁻¹ vs. 88.0 J K⁻¹ mol⁻¹) of fusion. [bmp][Tf₂N] shows a higher liquid phase heat capacity (589.5 J K⁻¹ mol⁻¹ at 298.15 K vs. 565.6 J K⁻¹ mol⁻¹) due to more atoms, but lower crystal phase heat capacities below 101 K. Both exhibit thermal history-dependent anomalies above 200 K, with [bmp][Tf₂N] displaying a broad anomaly at 140 K in its metastable crystal phase. Both are fragile liquids, showing significant changes in viscosity and heat capacity with small temperature variations near their glass transitions (181 K for [bmp][Tf₂N], 180 K for [bmim][Tf₂N]), characterized by non-Arrhenius behavior and large heat capacity jumps.
Applications
Pyrrolidinium-based ionic liquids are used across industries:
• Electrochemistry: Serve as electrolytes in batteries and supercapacitors due to high ionic conductivity and wide electrochemical windows.
• Catalysis: Enhance reaction efficiency and selectivity in organic synthesis.
• Pharmaceuticals: Exhibit antimicrobial and antifungal properties, aiding drug development.
• Green Chemistry: Low volatility and recyclability support sustainable processes.
• Material Science: Stabilize nanoparticles and produce advanced materials like cellulose fibers.
• Electronics: High ionic conductivity supports efficient ion transport in electrolytes, while thermal stability, low volatility, and non-flammability make them promising for cooling applications in energy storage and electronic devices.
