Usage

General Description

4,4'-DIIODODIPHENYLAMINE is a chemical compound with the molecular formula C12H10I2N2. It is a white to light yellow crystalline powder that is insoluble in water but soluble in organic solvents. 4,4'-DIIODODIPHENYLAMINE is primarily used as a raw material in the production of chemicals such as pharmaceuticals, dyes, and pigments. It is also used as an intermediate in the manufacture of antioxidants and stabilizers for polymers and plastics. However, 4,4'-DIIODODIPHENYLAMINE must be handled with caution as it is considered to be harmful if swallowed, inhaled, or in contact with skin, and may cause irritation to the respiratory system and skin. Therefore, proper safety precautions and protective measures should be taken when handling this chemical.

Selective para-iodination of methoxyarenes, phenols, and anilines with iodine in the presence of poly (4-vinylpyridine)-supported peroxodisulfate

A mild and efficient method for the direct iodination of methoxyarenes, phenols, and anilines using iodine and poly (4-vinylpyridine)-supported peroxodisulfate in acetonitrile solution, is presented. Selective para-substitution and also, the rather general applicability of this system is the advantage of the method.

Tuning the Photophysical Properties of Symmetric Squarylium Dyes: Investigation on the Halogen Modulation Effects

A series of symmetric squarylium dyes (SQDPA-X) with different halogen (X=F, Cl, Br, I) substituents have been developed. The photophysical properties could be facilely tuned by the halogen modulation effects. The strategy of incorporating different halogen substitutions into AIE active luminogens enables a facile approach for exploring new intriguing organic fluorescent dyes.
