Polyfluorene (PFO) is a light-emitting polymer due to its electroluminescence.

The building block of the polymere is the fluorene unit. Polyfluorenes are electroactive and photoactive materials with exceptional electrooptical characteristics which are used for the production of light-emitting diodes. Polyfluorenes can emit colors over the whole visible range.

For polyfluorene the fluorene molecules are connected at the 2 and 7 positions

The first blue light emitting polymerdiode was produced with a substituted polyfluorene (poly(9,9-dihexylfluorene)).
