1-Hexyl-1,4-diaza[2.2.2]bicyclooctanium bis(trifluoromethylsulfonyl)imide, CAS: 898256-50-3

Key Application:

1. Electrolytes and Electrochemical Media

• Suitable for high‑voltage electrochemical systems due to the wide electrochemical window of TFSI⁻.
• Used in lithium, sodium, and multivalent battery research as an additive or co‑solvent to improve ionic conductivity and interfacial stability.
• Compatible with metal deposition studies, including controlled electrodeposition of transition metals.
• Serves as a stable medium for redox‑active species in flow‑battery research.

2. Ion Transport and Conductivity Modifiers

• The bicyclic diammonium core provides high cationic mobility, making it useful in designing ionic‑liquid‑based ionogels and polymer electrolytes.
• Enhances mechanical stability and ionic transport in solid‑state electrolyte matrices.

3. Phase‑Transfer and Separation Processes

• Effective in biphasic catalysis and extraction systems due to its hydrophobic TFSI⁻ anion.
• Useful for selective extraction of metal ions, particularly soft or highly charged species.
• Can function as a tunable solvent for CO₂ capture or gas‑separation studies.

4. Catalysis and Reaction Media

• Provides a non‑volatile, thermally stable medium for organic synthesis under high‑temperature or microwave conditions.
• Supports acid‑catalyzed and metal‑catalyzed transformations where conventional solvents degrade.
• The rigid bicyclic cation can influence reaction selectivity in task‑specific catalytic systems.

5. Materials Science and Surface Engineering

• Used in preparing thin films, coatings, and ionically conductive layers.
• Compatible with polymer blending, enabling antistatic, conductive, or ion‑exchange properties.
• Can act as a templating agent for nanoporous materials.

6. Analytical and Spectroscopic Applications

• Serves as a stable matrix for mass spectrometry ionization studies.
• Useful in electroanalytical experiments requiring low vapor pressure and high thermal stability.
