Application

TPBi, or 1,3,5-Tris(1-phenyl-1H-benzimidazol-2-yl)benzene, is an essential component in optoelectronic devices, particularly OLEDs. It serves as an electron transport and exciton blocking material due to its electron-deficient nature, which makes it highly effective in these roles. With a low LUMO energy level of 2.7 eV, TPBi is an ideal host for both fluorescent and phosphorescent light-emitting systems. Its excellent electron transport capabilities and hole-blocking properties, attributed to its deep HOMO energy level (6.2/6.7 eV), allow it to simplify device structures by replacing other materials like CBP and Alq3. Additionally, TPBi can function as an electron injection layer, enhancing electron injection and contributing to hole-blocking and exciton confinement when used at the Alq3/Cs2O3 interface.
