Usage

General Description

4,4'-Bis((4-bromophenyl)phenylamino)biphenyl, also known as BPA-4, is a chemical compound consisting of two benzene rings connected by a biphenyl linker and substituted with 4-bromophenyl and phenylamino groups. It is commonly used as a building block in the synthesis of organic electronic materials such as organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and organic field-effect transistors (OFETs). BPA-4 is known for its high thermal stability, good charge transport properties, and efficient light emission, making it a valuable component in the development of advanced electronic devices. However, it is important to handle and use this compound with care, as it may have potential health and environmental risks if not properly managed.

Synthesis of triphenylamine (TPA) dimers and applications in cell imaging

A variety of triphenylamine (TPA) are shown to undergo C–C bond formation using quinone-based chloranil/H+ reagent as the metal free oxidative system to afford triphenylamine dimers very conveniently. Then, TPA dimers have been further converte

Oxidative Dimerization of Triarylamines Promoted by WCl6, Including the Solid State Isolation and the Crystallographic Characterization of a Triphenylammonium Salt

The triphenylammonium salt [NHPh3][WCl6], 1, and the product of the C-C dimerization of triphenylamine, Ph2N(C6H4)2NPh2, 2, were afforded from the reaction between WCl6 and NPh3 in CH2Cl2. Compound 2 was isolated in 43% yield upon hydrolysis of the reaction mixture. The X-ray structure of 1 provides the first crystallographic characterization of the triphenylammonium ion. Combined EPR and DFT studies gave insight into the reaction mechanism, and allowed the identification of WCl5···[Cl(C6H4)NPh2] as a presumable key intermediate. The reactions of WCl6 with 4-bromotriphenylamine, 4,4′-dimethyltriphenylamine, 9-phenylcarbazole, followed by hydrolytic treatment, led to the dimerization products 3-6, in admixture with variable amounts of the parent amines. N,N,N′,N′-tetrakis(4-bromophenyl)-[1,1′-biphenyl]-4,4′-diamine, 3, was isolated in 60% yield from the reaction of WCl6 with 4,4′-dibromotriphenylamine.
