Abstract
Abstract Buckminsterfullerene, C 60, was prepared in gram quantities by contact arc vaporization of a graphitic soot followed by extraction with toluene. After evaporation of toluene, the solid residue was characterized by mass spectrometry, high-performance liquid chromatography, IR- and UV-spectroscopy, X-ray diffraction and electron microscopy. The IR spectrum showed bands at 1429, 1183, 577 and 528 cm−1. Broader features were also observed in the UV (the strongest at 332, 270 and 208 nmrpar;. The transmission micrographs of typical crystals of the C60 show thin platelets, rods and stars with hexagonal symmetry. Analysis of X-ray diffraction and electron diffraction data confirms that the molecules have the anticipated ‘fullerene’ structure. The solid-state and molecular properties of C60 can now be studied in detail.
