Background Art

[0002] 4,4'-Bibenzo[p]indeno[7,1,2-ghi]chrysenylidene has 12 six-membered rings and 2 five-membered rings, and is a fragment corresponding to a partial structure having 90% of the carbon atoms of buckminsterfullerene C60 (see the following chemical formula). It is a polycyclic aromatic hydrocarbon (PAHs) having a typical non-planar π-conjugated system structure and is an organic molecule with 54 carbon atoms. Since it is a fragment structure of C60, it is expected to have properties similar to those of organic electronics materials and organic semiconductor materials similar to C60. Also, since it is a partial structure of C60, it is expected to have various possibilities as carbon materials.
