Pyrene is a fluorescent polycyclic aromatic hydrocarbon. It is useful as a proximity sensor – when two pyrene residues are spaced close to each other, they exhibit easily detectable excimer fluorescence.
Pyrene’s fluorescence emission spectrum is very sensitive to solvent polarity, so pyrene has been used as a solvent environment dependent probe.
