General description

6,13-Diphenylpentacene (DPP) is a fluorescent dye which gives rise to saturated red emission when used as a dopant in organic light emitting diodes (OLEDs). It is also used as a p-type semiconductor in organic electronics like thin film transistors, solar cells and diodes. †

Application

  • Used as a small molecule electron donor or p-type semiconductor in solution processed organic solar cells.
  • Used as a red emitting dopant in organic light emitting diodes (OLEDs).
  • Used as a high mobility charge transport material in organic thin film transistors (OTFTs).
