In Situ Generation of Functionality in a Reactive Haloalkane-Based Ligand for the Design of New Porous Coordination Polymers

Herein, we report new porous coordination polymers (PCPs) via a facile synthetic approach called “in situ generation of functionality in the ligand”. Upon a synthetic process of PCPs, a neutral (−CH2OH) or a cationic functionality (−CH2-[4,4′-bipyridine]+) was generated on a isophthalate ligand from a reactive haloalkane (−CH2Br) moiety, affording two new PCPs. The PCPs have two-dimensional layered structures with large potential solvent-accessible voids for CO2 adsorption.
