Description

Lanthanum Tris[Bis(Trimethylsilyl)Amide] is a highly reactive organolanthanum compound primarily used as a versatile precursor in advanced materials synthesis and organic transformations. Its value lies in its role as a potent lanthanum source for depositing high-purity lanthanum-containing films and as a catalyst or reagent in specialized organic and organometallic chemistry. This product is essential for researchers and manufacturers in the semiconductor, OLED, and specialty chemical industries who require high-purity metal-organic precursors for vapor deposition processes or for developing novel catalytic systems.

Application

• Chemical Vapor Deposition (CVD) & Atomic Layer Deposition (ALD): A critical precursor for depositing lanthanum oxide (La₂O₃) and other lanthanum-based high-κ dielectric films in semiconductor manufacturing.
• Advanced Materials Synthesis: Used in the synthesis of novel lanthanum complexes, organometallic frameworks, and single-source precursors for nanomaterials.
• Catalysis Research: Serves as a catalyst or catalyst precursor in organic reactions, including polymerization, hydroamination, and other bond-forming transformations.
• Phosphor and OLED Material Development: Employed in the research and production of lanthanum-doped phosphors and electroluminescent materials for display and lighting technologies.
• Academic & Industrial R&D: A key reagent for exploring new synthetic pathways and developing novel compounds in inorganic and organometallic chemistry laboratories.
