Description générale

4,4′-Dipyridyl (BPY) is an organic linker mainly used in the preparation of coordination polymers. It is a pyridine derivative in which pyridyl groups can rotate along the carbon-carbon structure. It can be used as a catalyst for photoelectrochemical reduction.
4,4′-bpy is popularly used to bridge metal centers to form coordination polymers with novel properties. 4,4′-bpy ligands can mediate electronic effects between paramagnetic metals ions by stabilizing the magnetic ordering.

Application

4,4′-Dipyridyl (4,4′-bipyridine, 4,4′-bpy) and Co (NCS)2 solutions were interdifussed to form single crystals Co(NCS)2(4,4′-bipy)2·2(CH3CH2)2O and Co(NCS)2(4,4′-bipy)2·2(CH3CH2)2O.
BPY is a ligand that forms a network between the transition metals which results in the formation of coordination bond. Hybrid nanosheets can be prepared by using a coordination polymer and BPY as a complex linker. It consists of two active sites which can be used for the development of drugs.

Graphene in Biotechnology

Graphene has emerged as the new wonder material. Being only one atom thick and composed of carbon atoms arranged in a hexagonal honeycomb lattice structure, the interest in this material has exploded exponentially since 2004 when it was first isolated and identified using a very simple method.
