The supramolecular nanoarchitectures, C60/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 C60/ferrocene hexagonal nanosheets had a size of ca. 9 μm and the formulation C60(ferrocene)2. A strong charge-transfer (CT) band between ferrocene and C60 was observed at 782 nm, indicating the presence of donor−acceptor interaction in the nanosheets. Upon heating the nanosheets to 150 °C, the CT band disappeared due to the sublimation of ferrocene from the C60/ferrocene hybrid, and C60 nanosheets with an fcc crystal structure and the same shape and size as the C60/ferrocene nanosheets were obtained.
