Abstract
Disclosed is a novel method for the selective molecular conversion of raw material carbon nanotubes containing a mixture of metallic carbon nanotubes and semiconductive carbon nanotubes in a manner that is based on the electrical properties or diameter of the carbon nanotubes. The present invention causes a photoreaction of raw material carbon nanotubes containing a mixture of metallic carbon nanotubes and semiconductive carbon nanotubes with a disulfide or a sulfide of the following formula (I) or (II) (wherein Rand Reach independently represent a hydrocarbon group that may have a substituent) in an organic solvent that contains the raw material carbon nanotubes and the disulfide of the formula (I) or the sulfide of the formula (II), so as to selectively functionalize the metallic carbon nanotubes, or functionalize the carbon nanotubes diameter selectively.
