Abstract
In the present research work, we report a facile, in-situ, and seedless-based synthesis method of cubic gold nanoparticles at room temperature by using thioether oligomer ligand DDT-P4VP [dodecanethiol-poly(4-vinylpyridine)] as a functionalization and stabilization agent. Thioether oligomer ligand was synthesized by bulk radical polymerization in the presence of dodecanethiol, while; the synthesis of cubic gold nanoparticles was carried out by a reduction reaction by NaBH4 in the presence of the pre-synthesized thioether oligomer ligand. The effect of stirring condition on the growth of nanoparticles and their final morphology has been investigated. Synthesized thioether oligomer ligand and gold nanoparticles were thoroughly characterized using numerous techniques such as Size Exclusion Chromatography (SEC), Fourier Transform Infrared Spectroscopy (FTIR), Proton Nuclear Magnetic Resonance Spectroscopy (1H NMR), Transmission Electron Microscope (TEM), and UV − visible spectroscopy.
