Coronene ( hexabenzobenzene ) belongs to the polycyclic aromatic hydrocarbons , more precisely to the circulenes . The molecule consists of six fused benzene rings (although when using the circle to denote aromatic rings, some authors also put a seventh circle in the inner ring).
Coronene is a yellow to gold powder made of thread-like particles or needle-like crystals. The solid melts at 438-440 ° C, boils at 525 ° C, is insoluble in water and soluble in non-polar solvents with slightly blue fluorescence. Coronene is very stable and has a very low vapor pressure . The coronene molecule is about 1 nanometer in size; it can be made visible with a scanning tunneling microscope .
