System for Living ROMP of a Paramagnetic FeCl₄^–-Based Ionic Liquid Monomer: Direct Synthesis of Magnetically Responsive Block Copolymers

Influence of metal-coordinating comonomers on the coordination structure and binding in magnetic poly(ionic liquid)s

“…These values correspond well with the 29.3 × 10 MPIL systems have generally been found to exhibit magnetic susceptibilities ranging between 10 × 10 −6 to 60 × 10 −6 emu g −1 depending on the metal complex concentration, the type of transition metals, and the diamagnetic contributions of the organic polymer chemistries. 7,14,84 MPIL systems with higher concentrations of the high spin paramagnetic MCl 4 n− species (where M = Fe 3+ , Co 2+ , etc.) have demonstrated higher susceptibilities 7,14 as was observed here for the MPIL copolymers with higher metal mole equivalencies.…”

A Review on Ionic Liquid Gas Separation Membranes

“…Chain growth polymerization (i) requires an IL monomer with an unsaturated or cyclic chemical structure that can be activated during the polymerization step ( Figure 5 ). Such a bond is often synthetically introduced into IL monomers (ILM) through the incorporation of methacrylic and methacrylamide [ 112 , 148 , 149 , 150 ], vinyl and styrene [ 116 , 151 , 152 , 153 , 154 , 155 ], or norbornene [ 156 , 157 , 158 ] or epoxy moieties. The sheer number of these reports demonstrates the applicability of this approach and underlines its advantages.…”

Terbium based (poly)ionic liquids for anti-counterfeiting and droplet manipulation

“…14 Common cations include 1,3-dialkyl-imidazolium, N-alkyl-pyridinium and tetraalkyl-ammonium, 15 while the anions are usually FeX 4 − , 16 CoX 4 − , 17 or MnX 4 2− (X = Cl, Br or BF 4 ). 18 Magnetic poly(ionic liquid)s (MPILs) [19][20][21][22] are polymers with a magnetic ionic liquid in each repeating unit. The magnetism of magnetic ionic liquids and magnetic poly(ionic liquid)s (M(P)ILs) is generated by high-spin transition metals in anionic complexes.…”
