Hexacyclic compounds

Hexacene is an aromatic compound consisting of six linearly-fused benzene rings. It is a blue-green, air-stable solid with low solubility.

'Benzo[ghi]perylene' is a polycyclic aromatic hydrocarbon with the chemical formula C22H12.

Anthanthrene (dibenzo[def,mno]chrysene) is a polycyclic aromatic hydrocarbon (PAH) primarily formed during the incomplete combustion of organic materials such as fossil fuels, wood, and tobacco. It is a golden-yellow, odorless solid, and is often released as solid particulate matter attached to soot or aerosols. Unlike other PAH molecules, it lacks a "bay region", a structural pocket that increases reactivity of the molecule. Due to its high lipophilicity, anthanthrene has low water-solubility, and tends to accumulate in lipid-rich environments.

Zethrene ('''''') is a polycyclic aromatic hydrocarbon consisting of two phenalene units fused together. According to Clar's rule, the two exterior naphthalene units are truly aromatic and the two central double bonds are not aromatic at all. For this reason the compound is of some interest to academic research. Zethrene has a deep-red color and it is light sensitive - complete decomposition under a sunlight lamp occurs within 12 hours. The melting point is 262 °C.

Hippuristanol is a small molecule found in the coral Isis hippuris which was discovered by Jerry Pelletier and others of McGill University in Montreal, Quebec, Canada. It appears to have anti-viral activity and may hold promise as a cancer therapy. Binds to and inhibits the eukaryotic translation initiation factor protein eIF4A.

Dibenzpyrenequinone is a synthetic vat dye. It is a bright yellow solid. It can be produced by cyclization of 1,5-dibenzoylnaphthalene. Dibenzpyrenequinone is a precursor to Vat Orange 1.

Dibromoanthanthrone is a scarlet or orange-red-hue synthetic organic colourant.
