9,10-Bis(phenylethynyl)anthracene (BPEA) is an aromatic hydrocarbon with the chemical formula is C30H18. It displays strong fluorescence and is used as a chemiluminescent fluorophore with high quantum efficiency.
It is used in lightsticks as a fluorophor producing ghostly green light. It is also used as a dopant for organic semiconductors in OLEDs.
The emission wavelength can be lowered by substituting the anthracene core by halogens or alkyls. 2-ethyl and 1,2-dimethyl substituted BPEAs are also in use.
