Synthesis of end-cap precursor molecules for (6, 6) armchair and (9, 0) zig-zag single-walled carbon nanotubes

The synthesis of two precursor molecules for end-caps of single-walled carbon nanotubes, namely C60H30 for a (6, 6) nanotube and C54H24 for a (9, 0) nanotube, is presented. Further an attractive approach for the subsequent growth of the corresponding SWCNTs is discussed.
