Dicoronylene is the trivial name for a very large polycyclic aromatic hydrocarbon. It has 15 rings and is a brick-red solid. Its formula is . Dicoronylene sublimes under high vacuum, 0.001 torr, between 250 °C and 300 °C.
==Structure== Due to its large size and limited availability, the organic chemistry of dicoronylene is little known. Dicoronylene does undergo a Diels–Alder reaction with maleic anhydride on one or both of the central bay regions on either side of the bridging ring. The double bond of maleic anhydride forms two carbon–carbon bonds on the ends of the bay region, making a new six-membered ring. Heating removes the anhydride as carbon dioxide gas and gives the corresponding 16-ring and 17-ring PAHs.
