Metal-organic coordination polymer is formed by self-assembly through coordination bond between bidentate or multbentate organic ligand and central metal ion.
Results of analysis with IR and ESCA showed that ring -shaped conjugated structures exist in the films. Copper atom may be linked to the polymer either by covalent bond or coordination bond.
There could be a coordination bond between the silver atom and the hydroxyl group of tannic acid, which stabilize the Ag nanoparticles in the spatial reticulate structure of tannic acid.
