CARBON NANORING, METHOD FOR PRODUCING SAME, COMPOUND SUITABLE AS STARTING MATERIAL FOR PRODUCING THE CARBON NANORING, AND METHOD FOR PRODUCING THE COMPOUND

摘要

Disclosed are: a compound which is capable of accurately forming a carbon nanoring that is composed of a specific number of organic rings and has a definite diameter; a method for producing the compound; a method for efficiently producing a carbon nanoring; and a cycloparaphenylene obtained by the production method. Specifically disclosed is a carbon nanoring which is a compound obtained by bonding a specific number of organic ring groups. Also specifically disclosed is a method for producing a carbon nanoring, which comprises a modification step wherein a halogen atom in a U-shaped compound is modified into a boron compound, and a coupling step wherein the U-shaped compound is subjected to a coupling reaction. In this connection, the U-shaped compound is a novel compound that has a cyclohexane ring, a benzene ring and a specific organic ring group.
