Description
Reviews
1,3,5-Tris(1-phenyl-1H-benzimidazol-2-yl)benzene(TPBi), which is electron-deficient, is usually used as an electron transport layer material in optoelectronic devices. TPBi has a low LUMO energy level (2.7 eV), and can also be used as a host material for fluorescent and phosphorescent light-emitting systems. TPBiBecause of its excellent electron transport ability, and because of the very deep HOMO energy level (HOMO=6.2/6.7eV), it has hole blocking ability,Usually used to replace CBP(HBL)/Alq3(ETL) to simplify the device structure.
