1-Hexadecyl-3-methylimidazolium tricyanomethanide

Key Applications:

1. Surfactants, Self‑Assembly, and Soft‑Matter Structuring

• Acts as a cationic surfactant with strong micelle‑forming behavior in low‑polarity and mixed‑solvent systems.
• Supports liquid crystal templating, mesophase stabilization, and nanostructured material formation.
• Useful in colloidal stabilization where long‑chain imidazolium cations enhance dispersion in hydrophobic media.

2. Organic Synthesis and Catalysis in Low‑Polarity Media

• Serves as a hydrophobic ionic liquid solvent for reactions requiring low water activity or enhanced solubilization of long‑chain substrates.
• Facilitates phase‑transfer catalysis, particularly for transformations involving hydrophobic reactants.
• Provides a tunable microenvironment for acid‑ or base‑sensitive reactions, leveraging the weakly coordinating TCM⁻ anion.

3. Electrochemical and Interfacial Applications

• Forms stable, low‑volatility electrolyte phases for interfacial electrochemistry, especially where hydrophobicity and wide electrochemical windows are advantageous.
• Useful in electrode surface modification, enabling ordered monolayer formation due to the C16 chain.
• Supports ionic conduction in nonaqueous systems, including mixed organic solvents.

4. Nanomaterials and Surface Functionalization

• Effective as a structure‑directing agent for nanoparticles, nanorods, and mesoporous materials.
• Enhances surface passivation and hydrophobic coating formation on metals, oxides, and carbon materials.
• Enables controlled growth of anisotropic nanostructures through ionic‑liquid templating.

5. Extraction, Separation, and Partitioning

• Provides strong hydrophobic extraction capability for nonpolar organics, aromatic compounds, and long‑chain species.
• Useful in liquid–liquid extraction systems where low miscibility with water is required.
• Supports selective partitioning of neutral or weakly polar analytes in analytical workflows.

6. Antimicrobial and Bio‑Interface Studies

• Long‑chain imidazolium cations exhibit membrane‑active antimicrobial properties, making this IL relevant for mechanistic studies and formulation research.
• Supports bio‑interface modification where hydrophobic ionic layers are desired.
