General description

Gold(III) chloride is a Lewis acid with monoclinic structure. It is a hygroscopic and light-sensitive solid. It is frequently utilized to dope organic conducting compounds, to boost their conductivity. It also serves as a catalyst in organic synthesis and a precursor to synthesize gold nanoparticles for various electrochemical applications.

Application

Gold(III) chloride can be used:
  • As a dopant to fabricate graphene protection layer between PEDOT:PSS and ITO for perovskite solar cells. It helps to enhance the photoconversion efficiency by protection ITO and collecting holes.
  • To fabricate flexible and transparent electrodes for OLEDs. It fills the defects in graphene and improves current efficiency without affecting the transmittance.
  • As a precursor for green synthesis of gold nanoparticles.
