9,10-diphenylanthracene from xylene, monoclinic, micrograph, illuminated with black light

9,10-Diphenylanthracene , also known as DPA , is a slightly yellow-colored polycyclic aromatic hydrocarbon which is used as a fluorescent substance in fluorescent sticks. As a result of chemiluminescence, it emits blue light in this case.

It is also an organic semiconductor and serves as the starting material for the production of blue organic light-emitting diodes .

The chlorinated hydrocarbon formed therefrom, 2-chloro-9,10-diphenylanthracene , also serves as a phosphor in blue-green fluorescent sticks.
