Abstract
The prolific production of metal-organic frameworks (MOFs) based on conformational flexible ligands has drawn the researchers towards the growth of novel crystalline frameworks with desired attributes. This feature of conformation mobility on coupling with coordination preferences of metal ions provides a means to generate dynamic porous MOFs which responds on external stimuli. To this end, we have constructed Zn(II)/ Co(II) MOFs using flexible ligands i.e., 9,10-bis(imidazole-1-ylmethyl)antracene/9,10-bis(1H-triazole-1-ylmethyl)antracene and different substituted sulfonic acids later these coordination polymer has been employed for the tailoring of isostructural two dimensional flexible metal organic framework. All MOFs were characterized by IR, SC-XRD analysis and the thermal stability of the frameworks was supported by TGA/DSC analysis. Single crystal X-ray diffraction analysis reveals that the complexes are isostructural and show flexibility in the framework. The theoretical studies were also carried out by DFT energy calculation using B3LYP/LANL2DZ as a basis set. Furthermore, the photophysical properties of complexes in the solid state and adsorption studies are also investigated.
