Abstract
Provided is a novel method for efficiently separating a metallic SWNT and a semiconducting SWNT from single-walled carbon nanotubes (SWNTs). The present invention is a method for separating a metallic SWNT and a semiconducting SWNT from SWNTs, said method comprising: dispersing the SWNTs in a solution containing a low-molecular-weight compound having an alkyl chain moiety for exhibiting solubility in a solvent and an aromatic-ring-containing moiety for interacting with the SWNTs; and separating the dispersion into a solution fraction and a solid fraction.
