摘要：

In this Letter, P-cyclodextrin (P-CD) was employed as stabilizer in the synthesis of gold nanoparticles. Gold nanoparticles were synthesized by the reduction of HAuCl4 by NaBH4 in the presence of P-CD. Varying the ratio of P-Cl) to HAuCl4, isolated gold nanoparticles could be assembled into nanowires. The nanoparticles and nanowires were characterized by transmission electron microscopy, UV/visible spectroscopy, infrared spectroscopy and X-ray photoelectron spectroscopy. The decreased relative intensity of skeletal and ring vibration in FT-IR spectra and the negative shift of the Au4f(7/2) binding energy in XPS spectra confirmed that beta-CD was chemisorped on An nanoparticles via hydroxyl group.
