N-([1,1μ-biphenyl]-4-yl)-9,9-dimethyl-N-(4-(9-phenyl-9H-carbazol-3-yl)phenyl)-9H-fluoren-2-amine (BCFN) is an electron-rich material, with the HOMO energy level of 5.3 eV, the LUMO energy level of 2.2 eV and high hole mobility of 5.43 * 10-5 cm2V-1s-1. As a result, it is used as a hole-transport and hole-injection material in organic light-emitting diodes. BCFN has shown its advantages in improving the hole mobility of polymer-based hole transport layer; lower driving voltage of device, better efficiency, and higher EQE due to exciplex formation by utilizing in EML; and better device lifetimes in the combination of Ir(piq)2(acac) to act as an electron scavenger layer for an reported device.
BCFN is a good morphologically stable material with Tg of 125 °C and Td of 375 °C.
With a ET of 2.58 eV, BCFN is also a very good charge transporting layer material due to its large band gap (Eg = 3.1 eV) 2 for green, red and white phosphorescent organic light-emitting diodes (PhOLEDs).
