Covalent organic frameworks (COFs) bipyridine ligands

for synthesising COFs and their metal complexes for host-guest interactions


[3,3-Bipyridine]-6,6-dicarboxaldehyde (CAS number 1264748-06-2), also known under IUPAC name of 3,3'-bipyridine-6,6'-dicarbaldehyde, is a derivative of 3,3’-bipyridine functionalised with two aldehyde groups. [3,3-Bipyridine]-6,6-dicarboxaldehyde undergoes reactions with amines to synthesise Schiff bases. The formation of the imine on the meso-carbon and the imine in the pyridine ring can coordinate to metal centre constructing a stable 5-membered ring. A metal-organic polyhedra composed of FeII and the Schiff base ligand prepared from [3,3-bipyridine]-6,6-dicarboxaldehyde and aniline, exhibits selective anion binding to PF6- over CF3SO3- and BF4-.

The metal-organic complexes from [3,3-bipyridine]-6,6-dicarboxaldehyde based COFs display a reversible binding affinity towards fluorescent dyes. This property enables the design of indicator-displacement assays.
