Abstract
AbstractThis work presents synthesis and characterization of two cobalt‐based coordination polymers (CPs) prepared by using two positionally related pyridine‐2,6‐dicarboxamide fragment‐based ligands containing appended arylcarboxylic acid groups. While arylcarboxylate groups of ligands coordinate to the Co(II) ions to produce 2D CPs; the amidic N−H groups remain free and generate large cavities lined with hydrogen bonds. Such hydrogen bonding cavities based CPs were found to reversibly adsorb molecular iodine. The Lewis acidic Co(II) ions and metal‐coordinated labile solvent molecules in CPs promoted noteworthy heterogeneous catalysis for Friedel crafts reactions as well as multicomponent condensation reactions.
