N-Phenyl-4-biphenylamine（Cat No.:L037984）, also known as 4-(Phenylamino)biphenyl, is an aromatic amine consisting of a biphenyl core substituted at the 4-position with a phenylamino group. This compound is widely used in the development of organic electronic materials, including OLEDs, organic semiconductors, and hole-transport materials, due to its excellent thermal and oxidative stability. The extended conjugation between the biphenyl and phenylamino moieties enhances electron delocalization, supporting efficient charge transport. It also serves as a building block in dye chemistry and in synthesizing ligands or pharmaceutical intermediates, owing to its modifiable aromatic amine functionality.
