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. From time-of-flight measurements, values of electron mobilities for NPB and 2TNATA are (6-9) × 10-4 and (1-3) × 10-4 cm2 V s, respectively, under an applied electric field range of 0.04-0.8 MVcm at 290 K. An organic light-emitting diode that employed NPB as the ET material was demonstrated. The electron conducting mechanism of NPB and 2TNATA in relation to the Marcus theory [Rev. Mod. Phys. 65, 599 (1993)] from quantum chemistry will be discussed.
