NPNPB, full name N,N'-diphenyl-N,N'-di-[4-(N,N-diphenyl-amino)phenyl]benzidine, is one of the family members of triarylamines. NPNPB is electron rich and can be used as an electron-transport layer material for OLEDs and perovskite solar cells. Due to its electron-donating nature, NPNPB is also used together with electron acceptors (such as PO-T2T) to form exciplexes in highly-efficient thermally activated delayed fluorescence OLEDs.
