Anthracene a polycyclic aromatic hydrocarbon is an important moiety in supramolecular chemistry due to its size and shape and photophysical properties. Anthracene is colorless but exhibits a blue 400 500 nm peak fluorescence under ultraviolet radiation. It is purified by recrystallization and sublimation. 2 anthracene sulfonyl chloride 2 anthracenesulfonic acid chloride anthracene 2 sulfonic acid chloride empirical formula hill notation.

Crude anthracene crystallizes from a high boiling coal tar fraction. It is not very soluble in water. Benz a anthracene is a plate like solid and may have a greenish yellow fluorescence.

It is a member of a group of chemicals called polyaromatic hydrocarbons pahs. Structure properties spectra suppliers and links for. It is a component of coal tar anthracene is used in the production of the red dye alizarin and other dyes. Anthracene is a solid polycyclic aromatic hydrocarbon pah of formula c 14 h 10 consisting of three fused benzene rings.

Anthracene has two molecules in the unit cell and according to the davydov theory in dipole approximation the splitting between the two components corresponding to the two values of i in 3 1 is proportional to m2 where m is the molecular transition dipole moment. Its closed shelled huckel aromatic structure fluorescence property well resolved absorption and emission bands high fluorescence quantum yield and nanosecond lifetime makes it an ideal.
