“…The four imidazole-benzene derivatives have been reported in the literature, synthesized using similar coupling techniques [34][35][36]. 1,4-diimidazolebenzene, 1,3,5-triimidazo-lebenzene, and 1,2,4,5-tetraimidazolebenzene were prepared from the respective bromobenzene compounds via Ullmann couplings, with an excess of imidazole, K 2 CO 3 , and CuSO 4 •5H 2 O in NMP.…”

This work introduces a series of vinyl-imidazolium-based polyelectrolyte composites, which were structurally modified via impregnation with multivalent imidazolium-benzene ionic liquids (ILs) or crosslinked with novel cationic crosslinkers which possess internal imidazolium cations and vinylimidazolium cations at the periphery. A set of eight [C4vim][Tf2N]-based membranes were prepared via UV-initiated free radical polymerization, including four composites containing di-, tri-, tetra-, and hexa-imidazolium benzene ILs and four crosslinked derivatives which utilized tri- and tetra- vinylimidazolium benzene crosslinking agents. Structural and functional characterizations were performed, and pure gas permeation data were collected to better understand the effects of “free” ILs dispersed in the polymeric matrix versus integrated ionic crosslinks on the transport behaviors of these thin films. These imidazolium PIL:IL composites exhibited moderately high CO2 permeabilities (~20–40 Barrer), a 4–7× increase relative to corresponding neat PIL, with excellent selectivities against N2 or CH4. The addition of imidazolium-benzene fillers with increased imidazolium content were shown to correspondingly enhance CO2 solubility (di- < tri- < tetra- < hexa-), with the [C4vim][Tf2N]: [Hexa(Im+)Benz ][Tf2N] composite showing the highest CO2 permeability (PCO2 = 38.4 Barrer), while maintaining modest selectivities (αCO2/CH4 = 20.2, αCO2/N2 = 23.6). Additionally, these metrics were similarly improved with the integration of more ionic content bonded to the polymeric matrix; increased PCO2 with increased wt% of the tri- and tetra-vinylimidazolium benzene crosslinking agent was observed. This study demonstrates the intriguing interactions and effects of ionic additives or crosslinkers within a PIL matrix, revealing the potential for the tuning of the properties and transport behaviors of ionic polymers using ionic liquid-inspired small molecules.

“…In order to obtain Co-CPs with novel structures and functional properties, an useful strategy is introduced auxiliary N-donor ligands [43][44][45][46]. Using such tactics, our groups have reported some new Co(II)-cluster based mixed-ligand CPs with magnetism, gas adsorption and photocatalysis [5,8,20,[47][48][49][50][51].…”

Two new Co(II) coordination polymers(CPs), namely [Co 2 (bpe) 2 (Hbppc)] n (1) and [Co 3 (μ 3-OH)(bppc)(bpm)(H 2 O)]•3H 2 O (2) (H 5 bppc = biphenyl-2,4,6,3',5'-pentacarboxylic acid, bpe = 1,2-bis(4-pyridyl)ethene, bpm = bis(4-pyridyl)amine), have been obtained and characterized by elemental analysis, single-crystal X-ray diffraction, powder X-ray diffraction (PXRD), IR spectra and thermogravimetric analysis (TGA). 1 shows a binodal (4,6)-connected fsc net with a (4 4 •6 10 •8)(4 4 •6 2) topology, while 2 shows a binodal (5,7)-connected 3D network based on trinuclear [Co 3 (μ 3-OH)] 5+ units with unusual (3.4 6 .5 2 .6)(3 2 .4 6 .5 7 .6 5 .7) topology. Variable-temperature magnetic susceptibility measurements reveals that complex 1 shows ferromagnetic interactions between the adjacent Co(II) ions, whereas 2 is a antiferromagnetic system.

“…In the construction of Co-CPs, mixed-ligand assembly, such as multicarboxylates and N-donor ligands, has been widely utilized for tunability of structural frameworks [40][41][42][43]. In our previous work, we have reported several new Co(II)-cluster based mixed-ligand MOFs [44][45][46][47][48][49], As part of our ongoing interest in understanding the ability of the multicarboxylate to direct the assembly of Co(II)-organic systems, herein, we chose H 4 L to induce Co(II)-core aggregation, and different auxiliary N-donor spacers, bis(4-pyridyl)amine (bpm) with -NH-linker or 1,2-bis(4-pyridyl)ethene (bpe) with -CHCH-linker, are introduced to tune the structures of polymetallic Co(II)-clusters and thus the properties of the final network, resulting in two coordination polymers containing similar 1D Co(II) chains bridging by carboxylate groups in syn-anti fashion, [Co 2 (bpm)(H 2 O) 3 …”
