1,2-Dimethyl-3-propyl imidazolium Iodide, CAS: 218151-78-1

Key Applications:

• Redox‑Active Electrolytes for Dye‑Sensitized Solar Cells (DSSCs)
  • This iodide‑based ionic liquid is widely used as a non‑volatile electrolyte component in DSSCs, where its high ionic conductivity and thermal stability support efficient I⁻/I₃⁻ redox cycling. Its low vapor pressure improves long‑term device durability compared to volatile organic solvents.
• Electrochemical Systems and Charge‑Transfer Media
  • The iodide anion and imidazolium cation together provide a tunable medium for electron‑transfer reactions. 

• • Its stable ionic environment supports reproducible electrochemical measurements.
• Precursor for Tailored Ionic Liquid Synthesis

• • Hydrophobic ionic liquids (via anion exchange to PF₆⁻, BF₄⁻, TFSI⁻)
  • Task‑specific ionic liquids for catalysis, separations, and materials science
• Solvent and Co‑Solvent in Organic Synthesis
  • The compound functions as a polar, aprotic ionic medium. 

• • Its thermal robustness and ionic character enable reaction conditions not accessible with conventional solvents.
• Template and Structure‑Directing Agent in Materials Chemistry

• • The cation’s steric profile and charge distribution influence pore formation and morphology.
• Phase‑Transfer and Extraction Applications
  • The iodide counterion provides strong nucleophilicity, enabling the ionic liquid to act as a phase‑transfer catalyst.
