General description

Poly(9,9-di-n-octylfluorenyl-2,7-diyl) (PFO) is a blue light emitting fluorescent polymer with high electroluminescence quantum yield and chemical stability. It can form an emissive layer on the surface of the optoelectronic devices.


PFO can be used as a phase separated polymer that interacts with the conducting probes to define the effect of noise sources on σ-conjugated charge carriers. It is used to disperse single walled carbon nanotubes (SWCNTs), which can be further used in the fabrication of field-effect transistors (FETs).

Light-Emitting Polymers

Conjugated polymers with long range p-electron delocalization behave as processable organic “metals” in their doped state and as semiconducting materials in their neutral undoped state.1–3 Many undop...
