Pyrolysis of acetylene over quartz plates coated with various metal catalysts resulted in the formation of all-carbon nanostructures which were observed directly by scanning electron microscopy (SEM). The nanotubes were studied in detail using transmission electron microscopy (TEM), and appear to grow as ultra-thin tubes with a central hollow core and considerable thickening due to secondary pyrolytic...
Two new methanofullerenes, C 60 (CHCN) and C 60 (CBr 2 ), have been prepared by treating a mixture of [60]fullerene and either CH 2 BrCN or CHBr 3 respectively with LDA. The products were purified by silica gel column chromatography, characterised by EI-MS and IR, and shown by 13 C NMR to consist solely of 6-6 ring junction adducts.
