• Applications

  Poly(9,9-dioctylfluorene-alt-N-(4-sec-butylphenyl)-diphenylamine) (TFB) is a triarylamine based semiconductor with a band gap of 3 eV (HOMO and LUMO levels of 5.3 and 2.3 eV, respectively) and a relatively high hole mobility of 2 ×10-3 cm2 V-1 s-1.
  Due to its low ionisation potential and high hole mobility, TFB serves primarily as hole transport layer (HTL), hole-injection layer (HIL) and electron-blocking layer (EBL) material in organic electronic devices. When built into device as an interface material, TFB as an electron blocking layer will not only reduce the chance of electron leakage, but also reduce the possibility of exciton quenching between the interface of the active layer and charge transport layer (F8BT/MoOx for example). ;
