Design and Synthesis of Imidazolium-Mediated Troger's Base-Containing Ionene Polymers for Advanced CO₂ Separation Membranes.

ABSTRACT: It is highly desirable to integrate the CO₂ solubility benefits of ionic liquids (ILs) in polymeric membrane systems for effective CO₂ separations. Herein, we are exclusively exploring a series of four novel imidazolium-mediated Tröger's base (TB)-containing ionene polymers for enhanced CO₂ separation. The two diimidazole-functionalized Tröger's base monomers synthesized from "ortho"- and "para"-substituted imidazole anilines were polymerized with equimolar amounts of two different aromatic and aliphatic comonomers (α,α'-dichloro-p-xylene and 1,10-dibromodecane, respectively) via Menshutkin reactions to obtain four respective ionene polymers ([Im-TB(o&p)-Xy][Cl] and ([Im-TB(o&p)-C₁₀][Br], respectively).
