Peryleneorperileneis apolycyclic aromatic hydrocarbonwith thechemical formulaC20H12,occurring as a brown solid. It or its derivatives may becarcinogenic,and it is considered to be a hazardouspollutant.Incell membranecytochemistry,perylene is used as afluorescentlipidprobe. It is the parent compound of a class ofrylene dyes.
Reactions
[edit]Like other polycyclic aromatic compounds, perylene is reduced by alkali metals to give a deeply colored radical anion and a dianion. Thediglymesolvates of these salts have been characterized byX-ray crystallography.[3]
Emission
[edit]Perylene displays bluefluorescence.It is used as a blue-emitting dopant material inOLEDs,either pure or substituted. Perylene can be also used as an organicphotoconductor.It has an absorption maximum at 434 nm, and as with all polycyclic aromatic compounds, low water solubility (1.2 x 10−5mmol/L). Perylene has amolar absorptivityof 38,500 M−1cm−1at 435.7 nm.

The perylenemoleculeconsists of twonaphthalenemolecules connected by a carbon-carbon bond at the 1 and 8 positions on both molecules. All of thecarbonatoms in perylene aresp2hybridized. The structure of perylene has been extensively studied byX-ray crystallography.[4]
