Morphology study of linear metallo-supramolecular polymer films

At. force microscopy was used to study the thin film morphol. of metallo-supramol. polymers. Extended linear polymers were made through complexation of poly(ethylene glycol) pre-polymers with terpyridine end-groups by addn. of suitable iron and ruthenium salts. For polymers with poly(ethylene glycol) spacers, a double lamellar morphol. was obsd. This morphol. is lost upon melting at 50 Deg. For the polymer with a diethylene glycol spacer an amorphous film is formed that is stable up to 250 Deg
