Lead(II) acetylacetonate is primarily used in the field of materials science and chemistry as a precursor in the synthesis of various lead-based materials. It is commonly employed in the production of thin films and coatings through chemical vapor deposition (CVD) or atomic layer deposition (ALD) techniques. These films are utilized in electronic and optoelectronic devices, including sensors, capacitors, and photovoltaic cells. Additionally, it serves as a catalyst or reagent in organic synthesis, particularly in reactions involving the formation of complex organic compounds. Its stability and solubility in organic solvents make it a valuable component in the preparation of specialized polymers and coordination compounds.
