摘要

A new procedure for the modification of cuprous oxide nanospheres with p-sulfonated calix[8]arene (pSC8) receptors is reported. Cuprous oxide nanospheres were prepared by the reduction of CuSO_4 in pSC8 aqueous solution using hydrazine as a reducing agent. The products were ' characterized by powder x-ray diffractometry, transmission electron microscopy, scanning electron microscopy, Fourier transform infrared, ultraviolet-visible spectra, energy-dispersive x-ray, and thermogravimetry. The experimental results showed that uniform cuprous oxide nanoparticles were obtained at low concentration of CuSO_4 with the protection of pSC8 in aqueous phase. Meanwhile, at high concentration of CuSO_4, large hollow and solid nanospheres were synthesized, depending on the amount of pSC8, which was used as a bridge linker during the formation of the nanospheres.
