1-Hexylpyridinium iodide, CAS: 7324-00-7

Key Applications:

Solar Cells and Photovoltaic Materials

• Functions as an iodide source and ionic additive in dye‑sensitized solar cells (DSSCs), supporting the I⁻/I₃⁻ redox shuttle
• Enhances charge‑transport efficiency and ionic conductivity in liquid and quasi‑solid electrolytes
• Helps stabilize dye regeneration kinetics and improve long‑term device performance
• Useful in tuning interfacial behavior, recombination rates, and electrolyte viscosity in next‑generation photovoltaic systems

Phase‑Transfer and Ion‑Pair Catalysis

• Facilitates halide exchange, nucleophilic substitution, and oxidation reactions in biphasic systems
• Improves iodide transport into organic phases, accelerating reaction rates
• Supports method development where iodide activity must be precisely controlled

Electrochemical and Redox Chemistry

• Serves as a supporting electrolyte and iodide source in redox‑active systems
• Enables studies of I⁻/I₃⁻ equilibria, charge‑transfer kinetics, and electrode surface interactions
• Supports iodide‑mediated electrosynthesis and analytical electrochemistry

Materials Science and Thin‑Film Processing

• Acts as a structure‑directing ion in hybrid organic–inorganic materials
• Supports halide incorporation studies in perovskite‑related systems
• Useful for tuning morphology, crystallinity, and ion mobility in emerging materials

Solvent and Extraction System Design

• Provides a tunable cation for biphasic extraction, halide partitioning, and iodide‑selective separations
• Enables studies of hydrophobic ion pairing and solvent structuring in mixed‑phase systems

Supramolecular and Self‑Assembly Research

• Supports host–guest binding studies involving halides
• Useful in designing ion‑responsive gels, micelles, and soft materials
• Helps probe noncovalent interactions driven by iodide’s polarizability

Analytical Chemistry
