Volatile Iridium and Platinum MOCVD Precursors: Chemistry, Thermal Properties, Materials and Prospects for Their Application in Medicine

Interest in iridium and platinum has been steadily encouraged due to such unique properties as exceptional chemical inertia corrosion resistance, high biological compatibility, mechanical strength, which are the basis for their application medical practice. Metal-organic vapor deposition (MOCVD) is a promising method fabricate Ir Pt nanomaterials, multilayers, heterostructures. Its advantages include precise control of material composition microstructure processes at relatively low temperatures onto non-planar substrates. The development MOCVD inextricably linked with chemistry volatile precursors, viz., specially designed coordination organometallic compounds. This review describes synthesis methods various thermal properties, examples use MOCVD, including formation films bimetallics. Although metal acetylacetonates currently most widely used recently developed heteroligand Ir(I) Pt(IV) complexes appear be more both synthetic thermochemical aspects. Their main advantage ability by modifying several types ligands, making them tunable deposit different materials select combination compatible compounds obtaining bimetallic materials.
