Synthesis of paramagnetic polymers using ionic liquid chemistry

Novel pyrrolidinium-based polymeric ionic liquids with cyano counter-anions: High performance membrane materials for post-combustion CO2 separation

“…While the first one involves the synthesis of diallyldimethylammonium ionic liquid monomers with the desired anions followed by polymerization to obtain pyrrolidinium-based PILs with different functionalities [73][74][75], the second route is achieved through the anion exchange of the water soluble poly(diallyldimethylammonium chloride) with the appropriated salt [76][77][78][79][80][81][82][83]. The second route is undoubtedly less complex since it has the advantage of obtaining several pyrrolidinium-based PILs directly from the same initial precursor via a simple aqueous purification step [78].…”

“…Two main synthetic routes have been used to prepare pyrrolidinium-based PILs for several applications [73][74][75][76][77][78][79][80][81][82][83]. While the first one involves the synthesis of diallyldimethylammonium ionic liquid monomers with the desired anions followed by polymerization to obtain pyrrolidinium-based PILs with different functionalities [73][74][75], the second route is achieved through the anion exchange of the water soluble poly(diallyldimethylammonium chloride) with the appropriated salt [76][77][78][79][80][81][82][83].…”

Fast Oxidative Removal of Refractory Aromatic Sulfur Compounds by a Magnetic Ionic Liquid

“…7). From the slope of the linear fits to the data, the molar magnetic susceptibility of [C 3 H 6 COOHmim]Cl/2FeCl 3 was obtained as 45.2 × 10 -6 emu g -1 , which conformed well to the value reported in the literature [30].…”

Ionic Liquids and Polymeric Ionic Liquids as Stimuli-Responsive Functional Materials

“…Hamaguchi and co-workers appear the first to report the synthesis of magnetic liquids by transforming IL chlorides, C 4 ImC 1 Cl and NCC 3 ImC 1 Cl (1-butyronitrile-3-methylimidazolium chloride), into IL FeCl 4 À salts [166]. Mecerreyes and co-workers reported PIL with FeCl 4 À and FeBrl 4 À counter anions, including microgel PIL particles that could be recovered in a magnetic field [167]. Gradzieski and co-workers showed that microemulsions of water and a magnetic room-temperature ionic liquid stabilized by an ionic surfactant and decanol as cosurfactant exhibited normal structural properties [168].…”
