Ionenes are a class of ionic polymers in which the charged groups are incorporated within the polymer backbone. The combination of strong electrostatic interactions and the underlying molecular architecture can lead to a wide range of thermophysical behaviors, with applications ranging from gas separation membranes to electrochemical systems. In order to accelerate the investigation of these materials, we propose a coarse-grained molecular model for a poly(alkylimidazolium) ionene, based on the Martini 3 force field. Although all-atom molecular simulations of ionenes have been previously performed, to the best of our knowledge, coarse-grained models of imidazolium-based ionenes are yet to be developed or tested. We perform benchmark comparisons against all-atom molecular dynamics simulations, and then, we use the more computationally efficient coarse-grained model to investigate the ionene performance for the selective absorption of benzene from an octane−benzene mixture. Our results show good performance of poly(alkylimidazolium tetrafluoroborate) for benzene extraction from the mixture, in terms of selectivity and solubility.

“…The utility of ionenes has been demonstrated in separations and CO 2 capture [ 8 , 9 , 10 , 11 , 12 , 13 ], ion-exchange or conducting membranes [ 14 ], antimicrobial coatings [ 15 , 16 , 17 , 18 ], batteries [ 19 , 20 , 21 ], electrochromic devices [ 22 ], hydrogels and gelators [ 23 , 24 , 25 ], water treatment [ 26 ], and fiber applications [ 12 , 27 , 28 ]. Nearly all known ionenes bear cationic moieties such as ammonium, phosphonium, pyrrolidinium, pyridinium, triazolium, and imidazolium groups [ 8 , 14 , 20 , 22 , 23 , 29 , 30 , 31 , 32 , 33 , 34 ]. While variation of cationic and anionic groups in polyelectrolytes have been studied, there is limited work probing the specific effects of cation and anion variation in ionenes [ 35 , 36 , 37 ].…”

Designing Imidazolium Poly(amide-amide) and Poly(amide-imide) Ionenes and Their Interactions with Mono- and Tris(imidazolium) Ionic Liquids

Here we introduce the synthesis and thermal properties of a series of sophisticated imidazolium ionenes with alternating amide-amide or amide-imide backbone functionality, and investigate the structural effects of mono(imidazolium) and unprecedented tris(imidazolium) ionic liquids (ILs) in these ionenes. The new set of poly(amide-amide) (PAA) and poly(amide-imide) (PAI) ionenes represent the intersection of conventional high-performance polymers with the ionene archetype–presenting polymers with alternating functional and ionic elements precisely sequenced along the backbone. The effects of polymer composition on the thermal properties and morphology were analyzed. Five distinct polymer backbones were synthesized and combined with a stoichiometric equivalent of the IL 1-benzyl-3-methylimidazolium bistriflimide ([Bnmim][Tf2N]), which were studied to probe the self-assembly, structuring, and contributions of intermolecular forces when IL is added. Furthermore, three polyamide (PA) or polyimide (PI) ionenes with simpler xylyl linkages were interfaced with [Bnmim][Tf2N] as well as a novel amide-linked tris(imidazolium) IL, to demonstrate the structural changes imparted by the inclusion of functional, ionic additives dispersed within the ionene matrix. This work highlights the possibilities for utilizing concepts from small molecules which exhibit supramolecular self-assembly to guide creative design and manipulate the structuring of ionenes.

This focused mini-review highlights recent advances related to the design and applications of imidazolium ionenes and forward-looking perspectives. Creative strategies which employ established synthetic approaches and utilize the modularity of the imidazole moiety unlock great potential for tailoring both functional and structural features arising from precise spacing of ionic groups within the polymer backbone. As imidazolium ionenes draw more interest, increased sophistication of chemical modifications and material processing is occurring, with a corresponding shift toward more demanding applications. Synthetic routes for placement and sequencing of ionic content are discussed, in addition to recent approaches to control structure and self-assembly or tune behaviors of imidazolium ionenes and composites.
