General description

Zirconium(IV) acetylacetonate is a white crystalline organometallic solid widely used as a sol-gel precursor to synthesize Zirconium-based nanomaterials and thin films. It also finds application in the field of catalysis and polymer synthesis.

Application

Zirconium(IV) acetylacetonate can be used:
  • As a sol-gel precursor to synthesize zirconia nanoparticles with photocatalytic activity.
  • As an additive to improve the performance of the electron transport layer in perovskite solar cells.
  • To synthesize as-prepared zirconium acetylacetonate (a-ZrAcac) film as a cathode buffer layer in polymer solar cells. It exhibited an average power conversion efficiency (PCE) of 8.75% which is significantly improved than that of the devices with traditional Ca/Al cathode.
  • To synthesize high-κ zirconium oxide gate dielectric for Organic Field-Effect Transistors at low voltage operation.
  • To fabricate the conductive interlayers for quantum dot light-emitting devices(QLEDs), which enhances quantum efficiency, power efficiency, and longer operational lifetimes.
  • As a ring-opening initiator to synthesize biodegradable polyacids.
  • As a catalyst to synthesize polylactide terpolymers.
