1-Methyl-3-tetradecylimidazolium bis(trifluoromethylsulfonyl)imide, CAS: 404001-49-6

Key Applications:

Advanced Materials and Interfaces

• Serves as a high‑stability ionic liquid for modifying hydrophobic surfaces, including silica, carbon, and polymeric substrates.
• Used in preparing ionically conductive, low‑volatility coatings for membranes, separators, and thin‑film devices.
• Supports fabrication of amphiphilic ionic‑liquid–polymer composites with enhanced mechanical flexibility and thermal endurance.

Electrochemical Systems

• Functions as a non‑volatile, wide‑electrochemical‑window electrolyte for supercapacitors and electrochemical sensors.
• Enhances interfacial stability in metal electrodes due to its long alkyl chain, which promotes ordered interfacial layers.
• Applied in ionic‑liquid‑based lubricating electrolytes for microelectromechanical systems (MEMS) and triboelectric devices.

Tribology and Lubrication

• Acts as a hydrophobic, thermally stable lubricant additive for high‑temperature or vacuum environments.
• Reduces friction and wear on steel, ceramic, and alloy surfaces through formation of robust ionic boundary films.
• Suitable for ionic‑liquid‑based greases and semi‑solid lubricants requiring low volatility and strong surface affinity.

Extraction, Separation, and Solvent Systems

• Effective in liquid–liquid extraction of hydrophobic organic compounds, aromatic hydrocarbons, and metal complexes.
• Used in biphasic catalysis where long‑chain imidazolium ionic liquids provide phase separation and catalyst retention.
• Supports selective partitioning of dyes, pharmaceuticals, and hydrophobic analytes in analytical workflows.

Catalysis and Reaction Media

• Provides a low‑volatility, thermally stable medium for acid‑catalyzed, transition‑metal‑catalyzed, and organocatalytic reactions.
• Enhances reaction rates in systems benefiting from microphase separation or amphiphilic ionic environments.
• Useful in immobilizing homogeneous catalysts for reuse and improved turnover.

Surfactant and Self‑Assembly Applications

• Exhibits strong amphiphilicity, enabling micelle formation, vesicle stabilization, and structured liquid phases.
• Applied in templating mesoporous materials and directing nanostructure formation in sol–gel and polymerization processes.
• Supports dispersion of hydrophobic nanoparticles, carbon nanotubes, and graphene derivatives.

Thermal and Chemical Stability Applications

• Suitable for high‑temperature processing environments due to its stable NTf₂ anion and long‑chain cation.
• Used in formulations requiring resistance to oxidation, hydrolysis, and decomposition under demanding conditions.
