Supramolecular functional materials

The field of this invention relates to supramolecular functional materials, particularly to coordination networks, more particularly to coordination polymers, more particularly to metal based one-dimensional coordination polymers. The metal based one-dimensional coordination polymers comprises a repeat unit [L 1 -M-L 2 ] n where L 1 and L 2 are one of a plurality of carboxylate ligands and L 1 can be the same as L 2 , M is a metal, particularly a transition metal, and n is an integer from 1 to infinity. The metal based one-dimensional coordination polymers display one or more physico-chemical properties giving at least one functionality to the supramolecular material. Furthermore, a method of forming the metal based one-dimensional coordination polymers is provided by a chemical reaction between said organic ligand and said metal where said method comprises at least one selectable chemical reaction condition from the group comprising: volume of reaction vessel, material composition of reaction vessel, temperature, pressure, humidity and gas defining an atmosphere inside reaction vessel.
