benzanthracene · benzo(b)phenanthrene · 1,2-benzanthracene
Benz[a]anthracene or benzo[a]anthracene is a polycyclic aromatic hydrocarbon with the chemical formula C18H12. In February 2014, NASA announced a greatly upgraded database for tracking polycyclic aromatic hydrocarbons (PAHs), including benz[a]anthracene, in the universe. According to scientists, more than 20% of the carbon in the universe may be associated with PAHs, possible starting materials for the formation of life.
Diamantane (also called congressane) is an organic compound that is a member of the diamondoids. These are a cage hydrocarbons with structures similar to a subunit of the diamond lattice. It is a colorless solid that has been a topic of research since its discovery in oil and separation from deep natural gas condensates.
Perhydropyrene (16291-77-3, 2435-85-0)
Perhydropyrene is a hydrocarbon similar to pyrene. Single bonds with hydrogen replace the double bonds in the benzene rings.
bicyclo(2.2.1)heptene · b(2.2.1)heptene · bicyclo(2.2.1)heptane
Norbornane (also known as bicyclo[2.2.1]heptane) is an organic compound and a saturated hydrocarbon with chemical formula C7H12. It is a crystalline compound with melting point 88 °C. The carbon skeleton is derived from cyclohexane ring with a methylene bridge in the 1,4- position, and is a bridged bicyclic compound.
Cubane (C8H8) is a synthetic hydrocarbon molecule that consists of eight carbon atoms arranged at the corners of a cube, with one hydrogen atom attached to each carbon atom. A solid crystalline substance, cubane is one of the Platonic hydrocarbons and a member of the prismanes. It was first synthesized in 1964 by Philip Eaton and Thomas Cole.
Spiropentane is a hydrocarbon with formula C5H8. It is the simplest spiro-connected cycloalkane, a triangulane. It took several years after the discovery in 1887 until the structure of the molecule was determined.According to the nomenclature rules for spiro compounds, the systematic name is spiro[2.2]pentane.
Dodecahedrane is a chemical compound (C20H20) first synthesised by Leo Paquette of Ohio State University in 1982, primarily for the "aesthetically pleasing symmetry of the dodecahedral framework". It is the simplest hydrocarbon with full icosahedral symmetry. In this molecule, each vertex is a carbon atom that bonds to three neighbouring carbon atoms.
Cuneane (C8H8, Pentacyclo[188.8.131.52 2,4.03,7.06,8]octane) is a saturated hydrocarbon. Its name is derived from the Latin cuneus, meaning a wedge. Cuneane may be produced from cubane by metal-ion-catalyzed σ-bond rearrangement.
Iceane is a saturated polycyclic hydrocarbon with formula C12H18. It has a cage-like molecular structure, whose carbon skeleton can be viewed as three fused cyclohexane rings in the boat conformation; or as two such rings in the chair conformation, connected by three parallel (axial) bonds. The name "iceane" was proposed by the chemist Louis Fieser about a decade before the compound was first prepared.
CHRYSENE (65996-93-2, 50-32-8, 218-01-9)
Chrysene is a polycyclic aromatic hydrocarbon (PAH) with the molecular formula C 18H 12 that consists of four fused benzene rings. It is a natural constituent of coal tar, from which it was first isolated and characterized. It is also found in creosote at levels of 0.5-6 mg/kg.
Biphenyl (92-52-4, 68409-73-4)
diphenyl · diphenyl, 14C-labeled
Biphenyl (or diphenyl or phenylbenzene or 1,1′-biphenyl or lemonene) is an organic compound that forms colorless crystals. Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes xenyl or diphenylyl. It has a distinctively pleasant smell.
