Abstract
Carbon nanotubes (CNTs) having a desired diameter are selectively produced by reacting a carbon source with a cyclic compound in which multiple aromatic rings are continuously bonded. The reaction is preferably performed by supplying a gaseous carbon source under reduced pressure and heating. The cyclic compound in which multiple aromatic rings are continuously bonded is preferably a cyclic compound in which bivalent aromatic hydrocarbon groups are continuously bonded, or a modified cycloparaphenylene compound in which a cycloparaphenylene compound or at least one phenylene group of the cycloparaphenylene compound is substituted with a condensed cyclic group such as a naphthylene group.
