    摘要: Methods for the chemical modification of carbon nanotubes involve the derivatization of multi- and single-wall carbon nanotubes, including small diameter (ca. 0.7 nm) single-wall carbon nanotubes, with diazonium species. The method allows the chemical attachment of a variety of organic compounds to the side and ends of carbon nanotubes. These chemically modified nanotubes have applications in polymer composite materials, molecular electronic applications, and sensor devices. The methods of derivatization include electrochemical induced reactions, thermally induced reactions, and photochemically induced reactions. Moreover, when modified with suitable chemical groups, the derivatized nanotubes are chemically compatible with a polymer matrix, allowing transfer of the properties of the nanotubes (such as, mechanical strength or electrical conductivity) to the properties of the composite material as a whole. Furthermore, when modified with suitable chemical groups, the groups can be polymerized to form a polymer that includes carbon nanotubes.

    摘要: A process for diazotizing amines in organic solvents is shown. A solution or suspension of a diazotizable amine compound such as p-toluidine or 2-naphthylamine in an excess of a heterocyclic base which may be for example pyridine, quinoline, picoline, lutidine or mixtures thereof and which is inert toward the action of compounds capable of splitting off nitrosyl groups, is diazotized by contacting it with a compound capable of splitting off nitrosyl groups such as nitrosylsulfuric acid or nitrosyl chloride.
