General description

Poly[9,9-bis-(2-ethylhexyl)-9H-fluorene-2,7-diyl] (PFO) is a polyfluorene based conductive liquid crystalline material that can be used as a light emitting material. It forms a semiconducting layer to enhance the electroluminescence (EL) and performance of the photonic and optoelectronic devices.
Light-emitting, conjugated polymer exhibiting blue photo- and electroluminescence.

Application

Organic Semiconductor Laser Materials
PFO forms a π-conjugating polymeric system that can produce blue EL devices which include organic light emitting diodes (OLEDs), optical fibers and molecular electronic devices.
