MOFs with acs and Nbo topologies using flexible diisophthalate ligands: Influence of dihedral angle between phenyl rings on the crystal structure

Abstract

Research on the design, synthesis, and application of metal organic frameworks (MOFs) based on flexible ligands has attracted significant attention in recent years owing to their superior performance in applications such as gas adsorption and molecular separation. In this work, two acs-type MOFs and an Nbo-type MOF derived from three different flexible diisophthalate ligands were solvothermally prepared and structurally characterized by single crystal X-ray diffraction, powder X-ray diffraction, and thermogravimetric analysis. Analyses of the data revealed that the topologies of the MOFs were correlated to the dihedral angle between the phenyl rings in the ligands.
