    摘要： 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.

    摘要： PAH is subjected to C—H/C—B coupling using a specific boron compound, a palladium compound, and o-chloranil to produce a compound in which a C—H bond of the PAH is directly arylated regioselectively in a simple manner. When the substrate and the boron compound are appropriately selected, a larger PAH can also be obtained by further performing an annulation reaction after the coupling reaction. Similarly, when PAH is subjected to C—H/C—H cross-coupling using a specific aromatic compound, a palladium compound, and o-chloranil, a compound in which a C—H bond of the PAH is directly arylated regioselectively can be produced in a simple manner. When the substrate and the aromatic compound are appropriately selected in this case, a larger PAH can also be obtained by further performing an annulation reaction after the cross-coupling reaction.
