Abstract

A comprehensive investigation of the thermal decomposition of hydroxyl-terminated generation-4 polyamidoamine dendrimer (G4OH) films on gold was presented. Thermal decomposition of the dendrimer films on Au surfaces was also studied by temperature programmed desorption (TPD) and X-ray photoelectron spectroscopy (XPS) under ultrahigh vacuum conditions. Dendrimer decomposition was investigated by thermogravimetric analysis in both air and argon atmospheres. Infrared absorption reflection spectroscopy studies showed that, when the films were heated in air to various temperatures up to 275° C, the disappearance of the amide vibrational modes occurred at a lower temperature from the Pt-G4OH film.
