1-Hexadecyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, CAS: 404001-50-9

Key Applications:

1. Transport‑Property Studies in Ionic Liquid Systems

• Used as a model long‑chain imidazolium ionic liquid for probing how alkyl‑chain length affects ionic conductivity, viscosity, diffusivity, and ion‑pairing behavior.
• Supports structure–property correlations in molecular dynamics simulations, NMR diffusometry, and impedance spectroscopy.
• Serves as a benchmark IL for evaluating cation aggregation, micelle formation, and nano‑segregation, all of which influence macroscopic transport.

2. Soft‑Matter and Self‑Assembly Research

• The C16 chain promotes lyotropic liquid‑crystalline phases, enabling studies of ordered ionic domains and their impact on mass transport.
• Used to tune interfacial mobility in polymer–IL blends and ion‑conducting soft materials.

3. Electrochemical and Interfacial Systems

• Incorporated into electrolyte formulations where low volatility and hydrophobicity are required.
• Evaluated for its influence on charge‑transfer resistance, double‑layer structure, and ion mobility at electrode interfaces.
• Useful in screening ILs for low‑conductivity, high‑stability environments where transport limitations are part of the design space.

4. Surfactant‑Like and Amphiphilic Applications

• Acts as an ionic surfactant in nonaqueous media, enabling controlled aggregation that affects diffusion pathways and solvent structuring.
• Supports studies on mass‑transport modulation in emulsions, microemulsions, and IL‑rich biphasic systems.

5. Materials Processing and Thin‑Film Engineering

• Used as a templating agent in sol–gel and nanoparticle syntheses where ion mobility and domain segregation influence final morphology.
• Helps tune transport through porous matrices, especially in hybrid organic–inorganic materials.

6. Tribology and Lubrication Science

• Evaluated as a hydrophobic IL lubricant where viscosity, shear response, and ion mobility govern friction and wear behavior.
• Long‑chain structure provides boundary‑layer formation that affects interfacial transport under load.

7. Extraction, Separation, and Partitioning

• Applied in biphasic IL–organic extraction systems where diffusion coefficients and phase‑transfer kinetics are key performance metrics.
• Useful for studying how hydrophobic ILs mediate solute transport across interfaces.
