Uses

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).
OLED Device Performance:
BCFN increase the hole transport mobility of PVK (pure PVK: 2.09*10-9 V cm-1 S-1; 30% of BCFN in PVK: 9.86*10-7 V cm-1 S-1; 50% of BCFN in PVK: 1.15*10-5 V cm-1 S-1):

It is suitable to be used in R&D studies such as organic field-effect transistors (OFETs), molecular electronics, sensors, organic photovoltaics (OPVs), and organic light-emitting diodes (OLEDs).

Synthesis

1242056-42-3

General procedure for the synthesis of N-biphenyl-4-yl-9,9-dimethyl-9H-fluoren-2-amine from N-([1,1'-biphenyl]-4-yl)-9,9-dimethyl-9H-fluoren-2-amine and 3-(4-bromophenyl)-9-phenylcarbazole: 3-(4-bromophenyl)-9-phenyl- 9H-carbazole (9.6 g, 24 mmol) was dissolved in toluene and N-([1,1'-biphenyl]-4-yl)-9,9-dimethyl-9H-fluoren-2-amine (7.2 g, 20 mmol), tris(dibenzylideneacetonato)dipalladium (Pd2(dba)3, 0.05 equiv.), triphenylphosphine (PPh3, 0.1 equiv.), and tert-butyl sodium ( NaOt-Bu, 3 eq.). The reaction mixture was heated to 100 °C and stirred at reflux for 24 hours. After completion of the reaction, the resulting organics were extracted, the organic layer was dried with anhydrous magnesium sulfate (MgSO4), purified by silica gel column chromatography (eluent: ethyl ether/water), and finally the target compound was obtained by recrystallization to 13.8 g (yield: 85%).
