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. 2021-04-04 Anthracene | (C6H4CH)2 or C14H10 | CID 8418 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. Anthracene's emission spectrum peaks at between 400 nm and 440 nm.

But most commercial anthracene is still recovered from coal tar. In commerce, anthracene is mainly used as a starting material for the manufacture of 9,10-anthraquinone, which in turn is used to make colorants such as the red dye alizarin.

Procedure and Observations: A reflux apparatus was assembled. 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).
