Graphical Abstract

Abstract

Metal-organic frameworks (MOFs) represent a versatile and highly tunable class of porous coordination polymers. Herein, we present the synthesis of novel MOFs using different synthetic methodologies based on a quionoxaline-multifunctional flexible ligand and nickel ions. The organic ligand was prepared via aromatic nucleophilic substitution using 2,3-dichloroquinoxaline, and its structure and purity were confirmed by NMR spectroscopy. The successful formation of the MOFs was validated by single-crystal X-ray diffraction, powder X-ray diffraction (PXRD), and FTIR spectroscopy. The thermogravimetry revealed that these new materials are stable below 350 °C, and the analysis of the N2 adsorption–desorption isotherms confirmed the porous structure. Furthermore, the CO2 adsorption capacity at room temperature demonstrated that these materials have promising potential for carbon capture and mitigation applications.
