چکیده انگلیسی
The preparation and characterization of a group of new composites, namely, gold nanoparticles-cored dendrimers were reported. These materials were obtained by the reduction of hydrogen tetrachloroaurate phase-transferred into organic phase in the presence of poly(benzyl ether) alcohol dendrons with generation 2. These materials, possessing nanometer-sized gold particles at the core and dendritic wedges radially connected to the core by Au–O bonds, were analyzed by UV–vis spectroscopy, transmission electron microscopy (TEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX) and Fourier transform infrared spectroscopy (FTIR). A possible mechanism of the formation of Gold nanoparticles-cored dendrimers was proposed.
