Metallo-supramolecular polymers are new functional polymers that are composed of monomeric units held together by kinetically stable metal-ligand interactions.The supramolecular polymers have varieties of geometric architectures and topologic structures

such as linear

grafted

networked

dendritic polymers

etc

and possess useful properties such as optical

electronic

and magnetic property

which are expected to have potential applications in many fields such as biomedicine

molecular devices

nanomaterials science

catalysis and hydrogen storage. Herein

we briefly review the progress in metallo-supramolecular polymers containing pyridine groups in recent years.
