  • CARBON NANORING, METHOD FOR PRODUCING SAME, COMPOUND SUITABLE AS STARTING MATERIAL FOR PRODUCING THE CARBON NANORING, AND METHOD FOR PRODUCING THE COMPOUND
    Publication number: 20130041155
    Abstract: This invention provides: a compound for accurately forming a carbon nanoring that contains 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. The carbon nanoring of the present invention is a compound obtained by bonding a specific number of organic ring groups. The method for producing a carbon nanoring of the present invention 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. The U-shaped compound is a novel compound that has cyclohexane rings, benzene rings, and specific organic ring groups.
