Preparation and Optical Properties of Fullerene/Ferrocene Hybrid Hexagonal Nanosheets and Large-Scale Production of Fullerene Hexagonal Nanosheets

摘要

The supramolecular nanoarchitectures, C_(60)/ferrocene nanosheets, were prepared by a simple liquid-liquid interfacial precipitation method and fully characterized by means of SEM, STEM, HRTEM, XRD, Raman and UV-vis-NIR spectra. The highly crystallized CWferrocene hexagonal nanosheets had a size of ca. 9 μm and the formulation C_(60)(ferrocene)_2. A strong charge-transfer (CT) band between ferrocene and C_(60) was observed at 782 nm, indicating the presence of donor-acceptor interaction in the nanosheets. Upon heating the nanosheets to 150 ℃, the CT band disappeared due to the sublimation of ferrocene from the C_(60)/ferrocene hybrid, and C_(60) nanosheets with an fcc crystal structure and the same shape and size as the C_(60)/ferrocene nanosheets were obtained.
