1-Butyl-1-methylpyrrolidinium tricyanomethanide, CAS: 878027-72-6

Key Applications:

1. High‑Stability Ionic Liquid for Electrochemical Systems

• Serves as a thermally stable ionic liquid with a highly delocalized tricyanomethanide (TCM⁻) anion.
• Used in electrochemical cells, ionic liquid electrolytes, and redox‑active media where low viscosity and wide electrochemical windows are required.
• Supports research into next‑generation battery electrolytes, including organic redox systems and hybrid ion devices.

2. Conductive Media for Organic Electronics

• Employed as a tunable ionic conductor in organic field‑effect transistors (OFETs), electrochromic devices, and soft electronic interfaces.
• The TCM⁻ anion enhances charge mobility and reduces ion‑pairing, improving device responsiveness.

3. Solvent and Co‑solvent for Catalysis & Synthesis

• Functions as a polar, non‑volatile medium for transition‑metal catalysis, organocatalysis, and anion‑stabilized reaction pathways.
• The tricyanomethanide anion stabilizes reactive intermediates, enabling transformations that benefit from strong electron delocalization.

4. Template & Structure‑Directing Agent in Materials Chemistry

• Used in the preparation of nanoporous materials, coordination frameworks, and ionic‑liquid‑derived carbon materials.
• The TCM⁻ anion’s geometry and charge distribution influence pore formation and carbon microstructure during pyrolysis.

5. Thermal‑Stability Studies & Fundamental Ionic Liquid Research

• Serves as a model system for studying:
  • anion delocalization effects
  • ion‑pairing and transport
  • structure–property relationships in pyrrolidinium ionic liquids
• Frequently used in comparative studies with BF₄⁻, PF₆⁻, TFSI⁻, and other anions.

6. Antistatic & Surface‑Modification Research

• Investigated as a component in antistatic coatings, surface‑charge dissipative layers, and ionic‑liquid‑modified polymers.
• The TCM⁻ anion provides stable charge distribution that enhances surface conductivity without compromising polymer integrity.
