Electron transport in naphthylamine-based organic compounds
Two naphthylamine-based hole transporters, namely, N , N ′ -diphenyl- N , N ′ -bis(1-naphthyl)( 1 , 1 ′ -biphenyl)- 4 , 4 ′ diamine (NPB) and 4 , 4 ′ , 4 ″ -tris( n -(2-naphthyl)- n -phenyl-amino)-triphenylamine (2TNATA), were found to possess electron transporting (ET) abilities.
