Trihexyltetradecylphosphonium tricyanomethanide, CAS: 855788-60-2

Key Applications:

1. Catalysis and Reaction Media

• Serves as a non‑coordinating ionic medium for transition‑metal catalysis, particularly where suppression of ligand exchange or anion interference is required.
• Supports biphasic and multiphasic catalytic systems due to its hydrophobicity and immiscibility with water.
• Enhances selectivity in organometallic transformations by stabilizing reactive intermediates in a low‑polarity ionic environment.
• Useful as a recyclable solvent phase for homogeneous catalysts.

2. Electrochemical and Energy‑Related Applications

• Functions as a stable, wide‑electrochemical‑window ionic liquid for electrode interface studies.
• Suitable for low‑volatility electrolytes in high‑temperature or sealed electrochemical devices.
• The tricyanomethanide anion provides high ionic mobility and low viscosity relative to other hydrophobic anions, improving ion transport in specialized electrolytes.

3. Materials Processing and Surface Engineering

• Acts as a structuring agent or dispersant for hydrophobic nanoparticles, carbon materials, and metal oxides.
• Useful in templating or directing the assembly of soft materials due to its amphiphilic cation.
• Provides antistatic and charge‑dissipative properties in polymer blends and coatings.

4. Extraction, Separation, and Partitioning

• Effective in liquid–liquid extraction of hydrophobic organics, aromatic compounds, and metal complexes with low aqueous solubility.
• Enables selective partitioning in systems requiring minimal water uptake and high chemical stability.
• Can be immobilized on solid supports for chromatographic or membrane‑based separations.

5. Thermal and Chemical Stability Applications

• Suitable for high‑temperature reaction media where conventional organic solvents degrade.
• Provides a chemically inert environment for sensitive reagents, radicals, or reactive intermediates.
• Useful in formulations requiring long‑term stability and resistance to oxidation.

6. Antimicrobial and Antifouling Research

• Long‑chain phosphonium cations exhibit strong antimicrobial activity; this ionic liquid is investigated for coatings, surface treatments, and controlled‑release systems.
• Potential use in biofouling‑resistant materials for marine, medical, and industrial environments.
