Claim Text:
1. A method for enriching specific species of carbon nanotubes, comprising: contacting a composition of carbon nanotubes with one or more quinone compounds; reacting the carbon nanotubes with the quinone compounds; and separating the carbon nanotubes reacted with the quinone compounds from the unreacted carbon nanotubes, wherein the one or more quinone compounds are of Formula (I): wherein R R wherein R and R′ are each independently selected from the group consisting of H and C provided that the compound is not 2,3-dichloro-5,6-dicyano-1,4,-benzoquinone or tetrachlorobenzoquinone; wherein the contacting step comprises suspending the composition of carbon nanotubes in an organic solvent containing the one or more quinone compounds; and wherein the reacting step comprises incubating the suspension under conditions that allow the quinone compounds to form radicals that react with a specific species of the carbon nanotubes.
