| 1,3,5-Tris(1-phenyl-1H-benzimidazol-2-yl)benzene Usage And Synthesis |
| Applications | 2,2',2"-(1,3,5-Benzinetriyl)-tris(1-phenyl-1-H-benzimidazole), TPBi, being electron deficient, is normally used as electron transport layer material in optoelectronic devices. Having a low LUMO energy level (2.7 eV), TPBi is also used as host material for both fluorescent and phosphorescent light emitting systems.
In some cases, TPBI is used to replace CBP (HBL)/Alq3 (ETL) to simplify the device structure for its excellent electron transporting and also its hole blocking abilities with very deep HOMO energy level (HOMO = 6.2/6.7 eV). It has also been reported that TPBi could be used as electron injection layer material between Alq3 (ETL) and Cs2O3/Al (electrode). It suggested that TPBI thin layer at the Alq3/Cs2O3 interface facilitates the electron injection and is also involved with hole-blocking and exciton confinement.
