Abstract
The object of the present invention is to provide a method of accurately separating optically active CNTs with single (n, m), as well as optically active carbon nanotubes obtained by the method. A plurality of gel-filled columns are connected in series. An excess amount of carbon nanotube dispersion passes therethrough, so that carbon nanotubes with specific optical activities are adsorbed to each of the columns. The carbon nanotubes are eluted by an eluent. In this manner, optically active carbon nanotubes with specific structures can be separated with high accuracy.
