Bis(1-butyl-3-methylimidazolium) tetrathiocyanatocobaltate, CAS: 1245942-47-5

Key Applications:

Advanced Electrochemical Systems

• Serves as a redox‑active ionic liquid with a cobalt‑based tetrathiocyanate anion, enabling tunable electron‑transfer behavior in electrochemical devices.
• Used in the development of non‑volatile electrolytes for high‑temperature or high‑stability energy‑storage platforms.
• Supports research into ionic‑liquid‑based redox mediators for dye‑sensitized solar cells and next‑generation electrochemical sensors.

Coordination Chemistry and Catalysis

• Provides a stable, well‑defined cobalt coordination environment useful for studying ligand‑field effects, electron‑donor/acceptor behavior, and metal–ligand charge transfer.
• Employed as a functional ionic medium for catalytic transformations where transition‑metal centers and soft‑donor ligands enhance reaction selectivity.
• Enables mechanistic studies of thiocyanate‑rich cobalt complexes in homogeneous catalysis.

Materials Science and Functional Thin Films

• Utilized in the fabrication of conductive or magnetically responsive thin films due to the paramagnetic cobalt center and ionic‑liquid matrix.
• Supports research into hybrid organic–inorganic materials where metal–thiocyanate clusters contribute to tunable optical or electronic properties.
• Investigated for incorporation into polymer–ionic liquid composites to enhance ionic conductivity and mechanical stability.

Spectroscopy, Magnetism, and Fundamental Studies

• Serves as a model compound for probing cobalt(II) electronic structure using UV–vis, EPR, and vibrational spectroscopy.
• Used in magnetic‑susceptibility studies to understand spin‑state behavior in thiocyanate‑coordinated cobalt complexes.
• Provides a stable, low‑volatility medium for studying ion pairing, solvation, and structural organization in imidazolium‑based ionic liquids.

Solvent and Extraction Research

• Functions as a task‑specific ionic liquid for selective extraction of soft‑donor metal ions due to the tetrathiocyanate ligand environment.
• Explored in biphasic separation systems where metal–ligand interactions drive selective partitioning.
• Supports studies on metal‑ion transport, coordination equilibria, and solvent structuring in ionic‑liquid phases.
