139092-78-7 - Introduction
4,4 ',4'-Tris(carbazol-9-yl)-triphenylamine is an organic compound with the chemical formula [C6H4(C9H6N3)3]. The following is a description of its nature, use, preparation and safety information:
Nature:
4,4 ',4'-Tris(carbazol-9-yl)-triphenylamine is a yellow crystalline solid. It has good thermal stability and light stability. Its solubility is poor, almost insoluble in water at room temperature, but soluble in organic solvents such as alcohols and ethers.
Use:
4,4 ',4'-Tris(carbazol-9-yl)-triphenylamine is commonly used as an antioxidant and light stabilizer for organic photoelectric functional materials. It can be used in electronic devices, coatings, plastics and other fields to improve the light resistance and heat resistance of materials.
Preparation Method:
The preparation of 4,4 ',4'-Tris(carbazol-9-yl)-triphenylamine typically uses in-situ polymerization. A common synthetic method is by reacting aniline with Tri (tert-butyl)-4,4 ',4'-Tris(carbazol-9-yl)-triphenylamine under nitrogen protection to yield the desired product.
Safety Information:
4,4 ',4'-Tris(carbazol-9-yl)-triphenylamine has low toxicity under normal use conditions. But should avoid inhalation of its dust or contact with the skin. Appropriate protective equipment such as gloves, goggles and laboratory coats should be worn during handling. When accidentally into the eyes or mouth, should immediately rinse with plenty of water, and seek medical help. During use or storage, avoid contact with oxidants, strong acids or strong bases to avoid dangerous reactions.
