Tris(2,2,6,6-Tetramethyl-3,5-Heptanedionato)Lanthanum Tetraglymeadduct Key Features

High thermal stability

Its complex structure provides excellent thermal stability, making it suitable for CVD/ALD processes over a wide temperature range, with relatively controllable thermal decomposition pathways.

Good volatility

Compared to single β-diketone complexes, the addition of Tetraglyme improves evaporability and transport efficiency, making it suitable for the preparation of metal oxide films or lanthanum thin films.

High purity controllable

High-purity Tris(2,2,6,6-Tetramethyl-3,5-Heptanedionato)Lanthanum Tetraglymeadduct ensures uniform composition of deposited films and reduces the impact of impurities on electronic properties.

Compatible with various deposition environments

C43H79LaO11 is suitable for reduced pressure CVD, atmospheric pressure CVD, and some ALD systems, and can be used with different carrier gases (N₂/Ar) and oxidants (O₂, H₂O, O₃).

Tris(2,2,6,6-Tetramethyl-3,5-Heptanedionato)Lanthanum Tetraglymeadduct Main Applications

La-metal film deposition

Used in CVD/ALD for the preparation of metallic lanthanum thin films or lanthanum-doped functional thin films, it is commonly used in microelectronic device and thin film material research.

High-k dielectrics

Lanthanum-based oxides (such as La2O3) are used in the research of advanced gate dielectrics, storage dielectrics and optoelectronic materials due to their high dielectric constant.

Doped materials

It is used in the research and development of lanthanum-doped optical materials, transparent ceramics, special catalysts and battery materials, etc.

Organometallic chemistry

As a well-defined lanthanum(III) complex, it can be used as a starting material for ligand exchange reactions and a key precursor for exploring organometallic synthesis.

Precautions

  1. Because it undergoes thermal decomposition at high temperatures, prolonged exposure to high-temperature environments or heating above the recommended temperature should be avoided.

  2. Tris(2,2,6,6-Tetramethyl-3,5-Heptanedionato)Lanthanum Tetraglymeadduct is hygroscopic and should be stored in a dry, airtight container to avoid contact with water or humid air.

  3. The complex contains an organic β-diketone structure, which may be dangerous if it reacts with strong oxidizing agents. It should be stored separately.

  4. Wear appropriate protective equipment to avoid inhaling dust or vapors; if it comes into contact with skin, immediately rinse with plenty of water and a mild detergent.

  5. When using high-purity materials, weighing and transferring should be done in a glove box or under an inert atmosphere to avoid water and oxygen affecting the material quality.

FAQ

1. What are the storage requirements for C43H79LaO11?
