Solvothermal reduction-polymerization route to linear conjugated nitrile polymer nanowires and circular nanostructures
چکیده انگلیسی

Linear conjugated nitrile polymer nanowires and circular nanostructures were synthesized via a solvothermal (benzene) reduction-polymerization route involved the reaction of cyanuric chloride (C3N3Cl3) with metal potassium (K) at 300 °C. Experimental data suggested that this reaction results in the fracture of the triazine ring to form [CN]n chain with a C6H5group on the carbon. Transmission electron microscopy (TEM) and Field-emission scanning electron microscopy (FESEM) images show that the polymer nanowires have diameters of 20–40 nm and lengths of 1–10 μm and that the polymer circular nanostructures have diameters of 10–50 nm and shell thicknesses of 5–10 nm. X-ray diffraction (XRD) patterns indicated that the synthesized polymer has a moderate-crystallization. Elemental analysis (from CNH combustion) gives the approximative bulk composition of C7NH5. The chemical bonding and optical properties of the synthesized polymer have been investigated by Mass spectroscopy, X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), UV–vis spectroscopy, and Raman spectroscopy.
