Application

1,3,5-tris(N-phenylbenzimidazol-2-yl)benzene is utilized in OLED devices primarily as an electron transport and exciton blocking material. This compound, similar to TPBi, effectively serves in optoelectronic applications due to its electron-deficient nature. Its low LUMO energy level of approximately 2.7 eV allows it to function as a host material for both fluorescent and phosphorescent light-emitting systems. In some instances, it can replace traditional materials like CBP or Alq3 to streamline device configurations, thanks to its superior electron transport and hole-blocking capabilities. With a deep HOMO energy level around 6.2 to 6.7 eV, the compound not only enhances electron injection, particularly when used as an intermediary layer between materials like Alq3 and Cs2O3 but also contributes to hole blocking and exciton confinement, thus optimizing device performance.
