In Earth's ecosphere, coronene is considered a pollutant, but this polynuclear aromatic hydrocarbon redeems itself as an ultraviolet phosphor for charge-coupled devices (CCDs).
MOTW update:

Coronene is a polynuclear aromatic compound sometimes called “superbenzene”. It is considered a pollutant in Earth’s atmosphere, but it has value as an ultraviolet phosphor. Coronene was detected in carbon stars in 1995.
Earlier this month, Patrick Hemberger, Alexander M. Mebel, Ralf I. Kaiser, and collaborators at Paul Scherrer Institute (Villigen, Switzerland), Florida International University (Miami), and the University of Hawaii at Manoa (Honolulu) reported that molecular-beam experiments and electronic structure calculations provided evidence that coronene is formed in carbon stars via a complex series of gas-phase reactions.
