Confirming its structure required isolating enough Cgo to apply modern techniques of structure determination. A quantum leap in fullerene research came in 1990 when a team led by Wolfgang Kratschmer of the Max Planck Institute for Nuclear Physics in Heidelberg and Donald Huffman of the University of Arizona successfully prepared buckmin-sterfullerene in amounts sufficient for its isolation, purification, and detailed study. Not only was the buckminsterfullerene structure shown to be correct. 

Incidentally, the stormy interest in buckminsterfullerene started subsiding a few years after the initial discovery because the original discoverers only observed but failed to produce the substance, so no chemistry could have been performed on it. Wolfgang Kratschmer and Donald Huffman (Figure 1-10) and their students changed this situation in 1990 when they obtained quantities of C60 from graphite in a discharge experiment [25], Their work made the new substance commonly available. The buckminsterfullerene story had an appeal for a broad readership even beyond chemists [26],...

There remained considerable debate over whether the circumstantial evidence really supported the amazing icosahedral structure for C o until 1990, when milligram and higher quantities of C o were isolated and subjected to spectroscopic study. Wolfgang Kratschmer (1937- ) and Donald R. Huffman (1935- ), astrophysicists at the Max Planck Institute in Heidelberg and the University of Arizona, had collaborated...
