CVD and ALD nickel precursor
Nickelocene is used as a volatile organonickel source in chemical vapour deposition (CVD) and atomic layer deposition (ALD) of nickel-containing thin films and coatings. Its defined volatility and thermal behaviour suit micro- and nanoelectronics fabrication.
Organometallic and inorganic synthesis
As a representative 20-electron metallocene, it serves as a building block and reagent in organonickel chemistry, including the preparation of other nickel complexes and cyclopentadienyl-derived species.
Catalysis and inorganic chemistry
Nickelocene is employed as a nickel source in catalysis and inorganic chemistry research, supporting the study and development of nickel-based catalytic systems.
Materials science and nanomaterials
It is applied in materials science as a precursor route to nickel-bearing materials and nanostructures, where a soluble, sublimable metal source is required.
Laboratory reagent and reference compound
The compound is used as a research reagent and a well-defined reference metallocene for method development and analytical work in academic and industrial laboratories.
