Infobox disclaimer and references

Anthracene is a solid ultraviolet light.

Synthesis

A classic method for the preparation of anthracene in the laboratory is by cyclodehydration of o-methyl- or o-methylene-substituted diarylketones in the so-called Elbs reaction (named for the German chemist Karl Elbs).[citation needed]

Reactions

Anthracene has the ability to UV light. This results in considerable changes in the physical properties of the material.


The dimer is connected by two oxygen.

In most other reactions of anthracene, the central ring is also targeted, as it is the most highly reactive. anthraquinone, C14H8O2 (below).

Uses

Anthracene can also have a phenol and napthol, and hydroxyanthracene is also called anthrol, and anthracenol.[2][3] Hydroxyanthracene derivatives are aloe for example.[4][5]

Anthracene is an emission spectrum peaks at between 400 nm and 440 nm.

Bipedal derivative

In 2005, chemists at the University of California, Riverside developed the first bipedal molecule, 9,10-Dithioanthracene, which propels itself in a straight line when heated on a flat copper surface. Researchers believe the molecule has potential for use in molecular computers.
