We have developed a new catalytic reaction for connecting benzene rings to create an eight-membered ring structure, and established a precise and practical method of synthesis for three-dimensional nanocarbons.

The key to this method is a new reaction using a palladium catalyst which enables the formation of the octagonal structure. In this reaction, polycyclic aromatic hydrocarbon substrates connect to construct the octagonal structure and enable successful three-dimensional nanocarbon molecule synthesis.
