General description

Triphenylarsine is an organoarsenic compound mainly used as a ligand and reagent in organic synthesis. It can also be used as a vapor deposition precursor to prepare nanomaterials.

Application

Triphenylarsine can be used:
  • As a CVD precursor to prepare As-doped carbon nanotubes with enhanced activity and long-term durability for the oxygen reduction reaction.
  • As an arsenic source to synthesize InAs nanocrystals.
  • As a ligand to accelerate the reaction rate of the Stille coupling reaction.
  • To prepare trichromophoric sensitizer for dye-sensitized solar cells.
