    en.wikipedia.org/wiki/Anthracene

    Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C 14 H 10, consisting of three fused benzene rings. It is a component of coal tar. Anthracene is used in the production of the red dye alizarin and other dyes. Anthracene is colorless but exhibits a blue (400–500 nm peak) fluorescence under ultraviolet radiation. [13]

    en.wikipedia.org/wiki/Phenanthrene

    Phenanthrene is used to make dyes, plastics, pesticides, explosives, and drugs. It has also been used to make bile acids, cholesterol and steroids. [3] Phenanthrene occurs naturally and also is a man-made chemical. Commonly, humans are exposed to phenanthrene through inhalation of cigarette smoke, but there are many routes of exposure.

    As a result, while anthracene reacts with maleic acid, phenanthrene does not, and triphenylene is the most stable species of these three. [1] Three Clar structures with an increasing number of fused rings around a benzene moiety: anthracene (on the left), phenanthrene (in the middle), and triphenylene (on the right).

    A Polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings.Most are produced by the incomplete combustion of organic matter— by engine exhaust fumes, tobacco, incinerators, in roasted meats and cereals, [1] or when biomass burns at lower temperatures as in forest fires.

  6. Diboraanthracene - Wikipedia

    en.wikipedia.org/wiki/Diboraanthracene

    Diboraanthracene is a class of boron heterocyclic compounds in which two boron atoms substitute two carbon atoms in anthracene (C₁₄H₁₀), one of the typical polycyclic aromatic hydrocarbons (PAHs). The most well-studied diboraanthracene is 9,10-disubstituted-9,10-diboraanthracene (DBA) and its doubly reduced dianion (DBA²⁻).
