Anthracene has the ability to photodimerize with irradiation by UV light. This results in considerable changes in the physical properties of the material. The dimer is connected by two covalent bonds resulting from the [4+4] cycloaddition. The dimer reverts to anthracene thermally or with UV irradiation below 300 nm.

Preparation and properties of anthracene:
- It can be prepared by mixing 100 gram of zinc with 30 ml of alcohol, then the mixture is mixed well to get a paste form.
- Anthracene is a solid form hydrocarbon made up of three fused benzene circles, obtained from coal-tar or any other thermal pyrolysis residues.
- Anthracene is used in red-dye alizarine artificial processing. It's also used in wood additives, insecticides, and fabrics used for painting. Anthracene's Chemical Properties could be said to be-colorless, crystalline light yellow stable with bluish fluorescence.
- PAHs are molecules that contain several rings of benzene, and they are often considered polynuclear aromatic hydrocarbons.
