Polydioctylfluorene

Polydioctylfluorene (PFO) is a type of polymer that is used in the field of organic electronics. It is a conjugated polymer, meaning it has alternating single and double bonds, which allows it to conduct electricity. PFO is particularly known for its use in organic light-emitting diodes (OLEDs), where it emits blue light.

Structure and Properties

Polydioctylfluorene consists of a repeating unit of dioctylfluorene, a molecule with a fluorene core and two octyl side chains. The fluorene core is a polycyclic aromatic hydrocarbon, which gives PFO its conjugated structure and its electronic properties. The octyl side chains provide solubility in organic solvents and processability.

PFO is a blue-emitting polymer. It has a high photoluminescence quantum yield, making it efficient for use in OLEDs. It also has good thermal stability and excellent film-forming properties.

Applications

The primary application of PFO is in OLEDs, where it is used as the emissive layer. The high photoluminescence quantum yield of PFO makes it an efficient emitter of blue light. This is important in the creation of full-color displays, as blue is one of the primary colors needed.

PFO is also used in polymer solar cells, where it can serve as the electron donor material. In addition, it has been used in field-effect transistors and light-emitting electrochemical cells.
