US Patent 7250147 - Diazonium derivatized carbon nanotubes

http://www.freepatentsonline.com/7250147.html

The inventors of this patent are fairly well known names in molecular electronics (including James Tour) and include a fairly broad claim to using diazonium in derivitization. One indication that this could be an important patent is that wikipedia has a page discussing diazonium derivitized carbon nanotubes-http://en.wikipedia.org/wiki/Diazonium
Claim 1 reads:

1. A method comprising: (a) selecting a plurality of carbon nanotubes; and (b) reacting the plurality of carbon nanotubes with a diazonium specie to form derivatized carbon nanotubes, wherein the diazonium specie is formed in situ.
