Phosphorodithioate-functionalized ionic liquids: Synthesis and physicochemical properties characterization

Abstract

This study focuses on preparation and characterization of physicochemical properties of a series of phosphorodithioate-bearing ionic liquids. They displayed low glass transition temperatures, high thermal stability, and were hydrophobic in character. The results of their ligation capability toward Pd(II) via 31P NMR spectroscopy is also presented. The synthetic strategy has the potential to impart (EtO)2P(=S)S functionality to ionic liquids by providing the flexibility to incorporate long linkers and task-specific anion to enhance hydrophobicity.
