1-Dodecyl-3-methylimidazolium iodide, CAS: 81995-09-7

Key Applications

Surfactants and Interfacial Systems

• Functions as a cationic surfactant with strong interfacial activity due to its long C12 alkyl chain.
• Used to stabilize emulsions, dispersions, and micellar systems in chemical and materials research.
• Supports the formation of ordered self‑assembled structures, including micelles, vesicles, and thin films.

Nanomaterials and Colloidal Synthesis

• Serves as a structure‑directing agent in the preparation of nanoparticles, nanorods, and mesoporous materials.
• Enhances dispersion stability of carbon nanomaterials, metal oxides, and quantum dots in polar and nonpolar media.
• Facilitates ionic‑liquid‑templated synthesis of hybrid organic–inorganic materials.

Electrochemical and Energy‑Related Applications

• Used as an ionic liquid electrolyte component in electrochemical devices where hydrophobicity and high ionic mobility are required.
• Supports electrodeposition processes, especially for metals and semiconductors requiring controlled nucleation environments.
• Investigated for ion‑transport layers and interfacial modifiers in dye‑sensitized and perovskite solar cells.

Extraction, Separation, and Solubilization

• Acts as an extractant or phase‑transfer medium for hydrophobic organic molecules and metal ions.
• Improves solubility and transport of poorly soluble compounds in biphasic systems.
• Useful in liquid–liquid extraction workflows involving halide‑sensitive species.

Antimicrobial and Biological Interfaces

• Exhibits antimicrobial activity typical of long‑chain imidazolium salts, enabling use in antimicrobial coatings and surface treatments.
• Applied in studies of membrane disruption, lipid interactions, and biomolecular self‑assembly.

Catalysis and Reaction Media

• Functions as a tunable ionic medium for organic transformations requiring high polarity and thermal stability.
• Enhances reaction rates in phase‑transfer catalysis and supports immobilization of catalytic species.
