Questions And Answer

• Classification

  Hole-blocking layer (HBL) materials , Electron injection layer (EIL) materials, OLEDS, Organic photovoltaics, Perovskite solar cells.;

• Applications

  BPhen is widely used as a hole-blocking or exciton-blocking layer due to its wide energy gap and high ionisation potential.
  The phenanthroline unit is small, rigid, and planar, with extended π-electrons and short hopping lengths that facilitate electron mobility. The electron mobility of BPhen is about 5 × 10-4 cm2 V-1 s-1, which is about two orders of magnitude higher than that of Alq3.
  When doped with lithium, BPhen:Li is an excellent electron-transport material, and is often used as an electron-injection layer to enable ohmic contact to any electrode -- without the need to consider the work function alignments. ;

• Reactions

  1. Bidentate ligand and reagent for determination of iron.
  2. Ligand used in the copper-catalyzed protodecarboxylation of aromatic carboxylic acids.
