Molecular Engineering of Tetra(hetero)arylphosphonium Ionic Liquids: Thermally Robust, Photoluminescent Materials with Tunable Melting Thermodynamics
Ionic liquids (ILs) are deployed for high-temperature technologies, where sustained thermo-oxidative stability must be combined with additional functions in a single organic material. We report a second-generation library of 34 tetra(hetero)arylphosphonium cations paired with the [NTf2]− anion, spanning seven π-conju...
