1-Dodecyl-3-methylimidazolium hexafluorophosphate, CAS: 219947-93-0

Key Applications:

Solvent and Co‑solvent in Organic Synthesis

• Supports reactions requiring low‑volatility, thermally stable media.
• Useful in nucleophilic substitutions, phase‑transfer‑assisted transformations, and moisture‑sensitive processes.
• Enhances solubility of long‑chain organics and hydrophobic intermediates.

Electrochemical and Ionic Conductivity Applications

• Serves as a hydrophobic ionic liquid electrolyte with good electrochemical stability.
• Applied in electrodeposition studies, redox‑active systems, and ion‑transport investigations.
• Suitable for evaluating interfacial behavior at liquid–liquid and liquid–solid boundaries.

Surfactant, Self‑Assembly, and Soft‑Matter Systems

• Long C12 alkyl chain promotes micelle formation, vesicle assembly, and ordered nanostructures.
• Used in templating studies for mesoporous materials and controlled‑morphology nanomaterials.
• Supports investigations into amphiphilic ionic liquid behavior and critical micelle concentration (CMC) tuning.

Separation Science and Extraction

• Effective as an extractant or phase modifier in biphasic ionic liquid systems.
• Applied in metal ion extraction, hydrophobic analyte partitioning, and solvent‑free purification strategies.
• Enhances selectivity in liquid–liquid extraction due to its hydrophobic PF6– anion.

Materials Science and Thin‑Film Fabrication

• Used in polymer–ionic liquid composites to improve flexibility, conductivity, and thermal stability.
• Supports fabrication of ion‑conductive membranes and coatings.
• Useful in modifying surface charge, wettability, and interfacial adhesion.

Analytical Chemistry and Spectroscopic Studies

• Provides a stable, low‑volatility medium for NMR, UV‑Vis, and fluorescence studies.
• Enables investigation of solvation dynamics, ion pairing, and microenvironment polarity.
• Suitable for calibrating hydrophobic ionic liquid behavior in method development.

Catalysis and Reaction Engineering

• Functions as a non‑volatile reaction medium for acid‑catalyzed and metal‑catalyzed transformations.
• Can enhance catalyst dispersion and turnover in biphasic catalytic systems.
• Supports recyclable catalyst platforms due to its low vapor pressure and phase‑separation behavior.
