Abstract
The present invention relates to methods for the preparation of a carbon nanotube from an amino-functionalized carbon nanotube via an amino oxidation reaction. The carbon nanotube includes nitrogen based functional groups that are covalently attached to lattice carbons of the carbon nanotube, directly or via a chemical linker. The synthetic methods of the present invention allow the nitrogen based functional groups to be attached selectively to one of two distinct regions of the carbon nanotube, and thus enable the synthesis of a carbon nanotube having nitrogen based functional groups substantially concentrated on the ends and/or the sidewall of the carbon nanotube.
