Pentacene is a polycyclic aromatic hydrocarbon consisting of five linearly-fused benzene rings. This highly conjugated compound is an organic semiconductor.The compound generates excitons upon absorption of ultra-violet or visible light; this makes it very sensitive to oxidation.For this reason, this compound, which is a purple powder, slowly degrades upon exposure to air and light.

Anthracene | (C6H4CH)2 or C14H10 | CID 8418 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities 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.

[citation needed] Anthracene is commonly used as a UV tracer in conformal coatings applied to printed wiring boards. The anthracene tracer allows the conformal coating to be inspected under UV light. ANTHRACENE is a colorless solid; melting point 218 °C, blue fluorescence when pure; insoluble in water, slightly soluble in alcohol or ether, soluble in hot benzene, slightly soluble in cold benzene; transformed by sunlight into para -anthracene (C14H10)2.

Xylene (6 mL), anthracene (0.5 g), and maleic anhydride (0.25 g) … 2019-08-15 The melting point of anthracene ranges between 208 and 218 °C, mainly depending on the grade of purity. The value of 214 °C is adopted as the most representative value (purity ca. 95 - 96 %). The major differences between anthracene and phenanthrene lie in the melting point and the properties directly related to solubility (Table 13.2). Phenanthrene is purified as brown to white monoclinic crystals, and also has the characteristic faint aromatic smell. Like anthracene, phenanthrene is used in the production of dyes.
