1-Hexylpyridinium bis(trifluoromethylsulfonyl)imide, CAS: 460983-97-5

Key Applications:

Electrochemical Systems

• Serves as a hydrophobic ionic liquid electrolyte with wide electrochemical stability for lithium, sodium, and magnesium battery research.
• Used as a co‑solvent or additive to enhance ionic conductivity and suppress dendrite formation in metal‑anode systems.
• Supports stable electrode–electrolyte interfaces in supercapacitors and redox‑flow systems due to its low volatility and high thermal stability.

Separation Science and Extraction

• Functions as a tunable, non‑volatile extraction phase for metal ions, including rare‑earth and transition‑metal separations.
• Applied in biphasic ionic‑liquid extraction systems where hydrophobicity and TFSI⁻ coordination improve selectivity and phase disengagement.
• Used in supported ionic‑liquid membranes for gas separation and pervaporation.

Catalysis and Organic Synthesis

• Acts as a reaction medium for transition‑metal catalysis, enabling improved solubility of organometallic complexes.
• Provides a non‑coordinating, thermally robust environment for electrophilic and acid‑catalyzed transformations.
• Supports recyclable catalytic systems due to its negligible vapor pressure and phase‑separation behavior.

Materials Science and Polymer Engineering

• Incorporated into polymer matrices to enhance ionic transport, flexibility, and thermal stability in ion‑conducting films.
• Used in the preparation of ionogels and hybrid materials for flexible electronics and solid‑state devices.
• Serves as a plasticizer or dopant in conductive polymers such as PEDOT‑based systems.

Surface Science and Lubrication

• Employed as a boundary‑lubrication additive due to its thermal stability and ability to form low‑friction interfacial layers.
• Used in anti‑wear coatings and high‑temperature lubrication studies where conventional oils degrade.

Spectroscopy and Fundamental Studies

• Provides a model hydrophobic ionic liquid for studying ion pairing, solvation dynamics, and interfacial structure.
• Used in vibrational, NMR, and X‑ray scattering studies to probe ionic‑liquid organization and transport mechanisms.
