Abstract

In this study, we report the synthesis and characterization of a new bis(pyridyl)-coordinated platinum(II)-containing metallopolyyne polymer. It is found that this metallopolymer can act as a precursor towards the synthesis of Pt nanoparticles upon pyrolysis (600 °C, 5 h). The resultant nanoparticles were characterized by transmission electron microscope (TEM), energy-dispersive X-ray analysis (EDXA) and powder X-ray diffraction (PXRD). The results verify that monodisperse Pt nanoparticles with defined morphology can be obtained. This pilot study reveals the potential of fabricating patterned Pt nanoparticles by using various lithographic methods in the future.
