Selective Adhesion of Gold Nanoparticles onto Microcrystal Faces of Cyclodextrin/Octanethiol Inclusion Compound Produced by Magnetron Sputtering

摘要

This paper described the stable gold nanoparticles (AuNPs) onto microcrystal faces of acyclodextrin /octanethiol (αCD/OT) inclusion compound (IC) by means of magnetron sputtering technique was obtained. Comparison of the ~(13)C Cross Polarization Magic Angle Spinning Nuclear Magnetic Resonance (~(13)C CP-MAS NMR) spectra for pure IC with those for IC interacting with AuNPs evidenced different orientation of the guest into the channels of the matrix of αCD. Diffuse Reflections Spectroscopy for the sputtered gold nanospheres on the surface of αCD/OT showed the characteristic surface plasmon resonance. Transmission Electronic Microscopy (TEM) demonstrates that this technique produces AuNPs in a size range about 2-6 nm. Scanning electron microscopy (SEM) show the selective adhesion of AuNPs onto IC.
