Abstract Ionic polymers functionalized with hydroxyl, carboxyl, and amino groups can enhance the catalytic activity of catalysts. However, straightforward preparation bifunctional ionic containing abundant active sites hydrogen bond donors remains challenging. In this study, a series porous (BZIs) different (-NH2, -OH, -COOH) were prepared through simple one-pot Friedel-Crafts alkylation using benzimidazole derivatives benzyl bromide. The structures properties BZIs characterized by various techniques such as Fourier-transform infrared spectroscopy, X-ray photoelectron solid-state nuclear magnetic resonance scanning electron microscopy. Among catalysts (BZI-NH2, BZI-OH, BZI-COOH), BZI-NH2 exhibited highest recyclability, achieving yield 97% in CO2 cycloaddition. synergistic effect Br−, (-NH-, -NH2), N+ was found to contribute its superior performance. DFT calculations employed study bonds, BZI-OH on Using an example, mechanism proposed for between bromide ions catalyzing cycloaddition reaction.

Nitrogen-rich metal organic frameworks (MOFs) structures have a great potential for the chemical fixation of CO2. In this direction, we utilized highly efficient nitrogen-rich dual linker MOF nickel(ii) as heterogeneous catalyst in solvent-free CO2 into cyclic carbonates at ambient pressure. present work, nickel-MOF, Ni-ImzAdn, was synthesized from imidazole and adenine linkers under hydrothermal conditions (Imz = Imidazole Adn Adenine). The Ni-ImzAdn characterized thoroughly via various physicochemical analyses such FT-IR, SEM, EDX, EDX-mapping, XRD, ICP-OES, BET, BJH, TG-DTA, CO2-TPD, NH3-TPD. with adequate free nitrogen sites exhibit high catalytic activity cycloaddition styrene oxide (93% yield) attributed to synergistic effect strong Lewis acid base on catalyst, which were acquired by NH3-TPD respectively. addition, presented recyclable without significant loss after six reaction cycles low ion leaching (analyzed (ICP-OES)). Thermogravimetry-differential thermal analysis (TG-DTA) showed had stability up 318 °C.
