1-Decyl-3-methylimidazolium triflate, CAS: 412009-62-2

Key Applications:

Solvent and Medium for Organic Synthesis

• Supports reactions requiring low‑volatility, thermally stable media.
• Useful in alkylation, nucleophilic substitution, and acid‑catalyzed transformations where the triflate anion provides enhanced ionic conductivity and moderate coordinating ability.
• Enables biphasic or phase‑transfer‑like systems due to its amphiphilic C10 chain.

Electrochemical and Ionic Conductivity Applications

• Functions as a high‑conductivity electrolyte component in electrochemical cells, especially where hydrophobicity and wide electrochemical windows are desired.
• Suitable for electrodeposition studies and ionic‑liquid‑based capacitors where long‑chain imidazolium cations improve interfacial structuring.

Materials Processing and Polymer Science

• Acts as a plasticizing or ion‑conducting additive in polymer matrices, including PVDF, PMMA, and ionomer systems.
• Enhances flexibility, ionic mobility, and thermal stability in polymer electrolytes and membranes.
• Useful in templating or directing nanostructure formation in block copolymers due to its amphiphilic character.

Surfactant‑Like and Self‑Assembly Behavior

• The decyl chain imparts strong amphiphilicity, enabling micelle‑like aggregation in certain solvents.
• Supports formation of ordered soft materials, thin films, and structured liquids.
• Useful in dispersing nanoparticles or stabilizing colloidal systems where ionic surface interactions are required.

Catalysis and Phase Behavior Engineering

• Serves as a tunable medium for acid‑catalyzed and metal‑catalyzed reactions, leveraging the weakly coordinating triflate anion.
• Facilitates catalyst recycling and separation due to its low volatility and immiscibility with many organic solvents.
• Enables temperature‑dependent phase behavior useful for reaction control and product isolation.

Extraction, Separation, and Partitioning

• Effective in liquid–liquid extraction systems where hydrophobic ionic liquids enhance selectivity for aromatic, sulfur‑containing, or metal‑ion species.
• The long alkyl chain improves partitioning behavior and reduces miscibility with aqueous phases.

Nanomaterials and Surface Modification

• Useful as a stabilizing medium for metal nanoparticles, carbon nanomaterials, and metal oxides.
• Enhances dispersion quality and surface charge control in hydrophobic or mixed‑polarity environments.
