In chemistry, the organic compound triphenylene is a flat polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings. Triphenylene is isolated from coal tar. One molecule of triphenylene has delocalized 18--electron systems based on a planar structure. It has the molecular formula n8H12. Triphenylene is a fully-benzenoid PAH, meaning its structure is composed only of full benzene rings interconnected by carbon-carbon single bonds. The three benzene rings can be drawn as the three outer rings, with the central ring formed by one face of each and the three carbon-carbon single bonds.
