1-Dodecyl-3-methylimidazolium tetrafluoroborate, CAS: 244193-59-7

Key Applications:

1. Surfactants & Interfacial Engineering

• Functions as a surface‑active ionic liquid (SAIL) with strong amphiphilicity for tuning interfacial tension in aqueous and non‑aqueous systems.
• Supports emulsion formation, microemulsions, and colloidal stabilization, especially under thermal or chemical stress.
• Enables nanoparticle dispersion and controlled self‑assembly in soft materials and nanostructured films.

2. Extraction & Separation Processes

• Serves as a hydrophobic IL phase for liquid–liquid extraction of hydrophobic organics, dyes, and metal ions.
• Provides enhanced selectivity in ion‑pair extraction due to its long alkyl chain and low water miscibility.
• Used in supported ionic liquid membranes (SILMs) for gas and solute separations.

3. Electrochemical & Energy Applications

• Acts as a low‑volatility electrolyte component in systems requiring hydrophobic ILs.
• Enhances ionic conduction in polymer electrolytes, gels, and hybrid membranes.
• Applied in electrode surface modification to improve wettability and interfacial charge transfer.

4. Antimicrobial & Biointerface Applications

• Exhibits broad‑spectrum antimicrobial activity, particularly against Gram‑positive bacteria, due to its membrane‑disruptive C12 chain.
• Incorporated into coatings, films, and disinfectant formulations where non‑volatile, thermally stable antimicrobial agents are needed.
• Explored for biofouling‑resistant surfaces and controlled‑release matrices.

5. Soft Materials, Polymers & Nanostructures

• Functions as a structure‑directing agent in templated synthesis of mesoporous materials.
• Improves compatibilization and plasticization in polymer blends.
• Used in ionic liquid–based gels, surfactant–IL hybrid materials, and responsive soft matter systems.

6. Solvent & Reaction Media

• Provides a thermally stable, non‑volatile medium for organic transformations requiring hydrophobic ILs.
• Supports phase‑transfer catalysis and reactions involving hydrophobic substrates.
• Useful in microwave‑assisted synthesis due to strong absorption and thermal stability.
