4,4-二乙炔联苯 - Introduction
4,4-diethynylbiphenyl is an organic compound with the chemical formula C16H12. It is a solid with white crystals or powder. Its main properties are as follows:
1. Melting Point: about 150-152 degrees Celsius;
2. Boiling point: about 344-347 degrees Celsius;
3. Molecular weight: about 204.27g/mol;
4. Insoluble in water, soluble in organic solvents, such as toluene, ethanol, xylene, etc.
4,4-diethynylbiphenyl has a wide range of applications, including:
1. As a compound synthesis precursor in organic synthesis, used in the preparation of other organic compounds;
2. Used as a material in liquid crystal displays to enhance the display effect;
3. It is used as a material in organic electronics for the preparation of optoelectronic devices, light-emitting diodes and organic solar cells.
The method for preparing 4,4-diethynylbiphenyl mainly includes:
1. By Su(Suzuki) reaction: the reactants containing 4,4-dibromobiphenyl and ethynyl borate are reacted with palladium catalyst in a suitable solvent to obtain the product;
2. Through the Heck reaction: the reaction containing 4,4-dibromobiphenyl and vinyl compounds (such as ethylene), in the presence of palladium catalyst, under alkaline conditions reaction to obtain the product.
Regarding safety information, there are no public reports on the detailed toxicology and safety of 4,4-diethynylbiphenyl. However, as an organic compound, the following safety operations should be noted:
1. Avoid contact with skin and eyes, and use protective gloves and goggles if necessary;
2. Operate in a well-ventilated place to avoid inhaling aerosols or dust;
3. Avoid contact with combustible substances, away from open flame or high temperature source;
4. Storage should be sealed, away from the fire and oxidant.
When using 4,4-diethynylbiphenyl, it is best to operate according to the requirements of specific chemical reactions and relevant safety operation procedures. At the same time, understanding and compliance with relevant laws and regulations and guidance documents is also very important.
