N,N'-Di-1-naphthyl-N,N'-diphenylbenzidine, abbreviated as NPB, is an organic compound appearing as a pale yellow powder. It dissolves in organic solvents such as dichloromethane, diethyl ether, and benzene. It exhibits excellent thermal stability and electrochemical properties, along with a strong aromatic fragrance. NPB serves as a synthetic intermediate for optoelectronic functional materials and a functionalizing agent for carbon materials. Possessing favorable charge transport properties and luminescent characteristics, it finds extensive applications in organic light-emitting diodes (OLEDs), organic thin-film transistors (OFETs), and photovoltaic conversion devices.
