Mesitylene Tungsten Tricarbonyl Key Features

Excellent thermal stability and volatility

Mesitylene tungsten tricarbonyl exhibits significantly improved thermal stability while maintaining good volatility. This property makes it easier to transport and control in CVD/ALD processes, while reducing pipeline blockage problems caused by precursor decomposition.

Clear decomposition pathway and high-purity tungsten films

During the thermal decomposition of C12H9O3W, the mesitylene ligand can leave in its intact molecular form, significantly reducing the risk of carbon contamination. This characteristic makes it particularly suitable for preparing high-purity tungsten thin films, exhibiting excellent film quality and electrical properties in semiconductor interconnect processes.

Stable aromatic ring π-coordination structure

The coordination structure between the aromatic ring and tungsten is stable, facilitating storage and transportation while maintaining good reactivity.

Catalysis research

Mesitylene tungsten tricarbonyl can serve as a homogeneous catalyst precursor, participating in important organic transformation processes such as olefin metathesis and aldehyde reaction.

Organometallic synthesis

As a tungsten carbonyl precursor, C12H9O3W is used to synthesize derived tungsten complexes, expanding the organometallic chemical structure system.

Surface modification and functional coatings

In materials surface engineering, this compound can be used to prepare tungsten-based coatings with specific functions. By controlling the deposition parameters, coatings with different phases, from metallic tungsten to tungsten carbide, can be obtained to meet diverse needs such as wear resistance and corrosion resistance.

Preparation of functional nanomaterials

Utilizing the controllable decomposition property of C12H9O3W, tungsten-based nanoparticles and nanowires with uniform size can be prepared, providing high-quality materials for catalysis and energy fields.

Precautions

1. Store in a sealed, light-proof, and dry environment. It is recommended to protect it with an inert gas (such as nitrogen/argon).

2. Gloves and goggles must be worn during operation and the procedure must be carried out in a fume hood to avoid inhalation or skin contact.

3. Anhydrous and oxygen-free organic solvents should be used preferentially to avoid affecting the reaction activity and purity.

4. Small leaks can be collected with absorbent materials and should not be discharged directly into the sewer system.

5. Waste containing mesitylene tungsten tricarbonyl should be disposed of by a qualified professional organization in accordance with the regulations for the treatment of heavy metal organic waste.

FAQ

1. Can this compound be used in CVD or ALD processes?

It is mainly used for solution-phase catalysis and organometallic synthesis, and is not a mainstream CVD precursor, but it can be used as a special research reagent.

2. Does the darkening of the color of mesitylene tungsten tricarbonyl during storage indicate spoilage?

Darkening of the color may indicate partial decomposition. It is recommended to detect this using 1H NMR or infrared spectroscopy. If the characteristic infrared peaks of the carbonyl group change or new peaks appear, it indicates that the product has decomposed and repurification should be considered.
