TPBi (C45H30N6) for OLED and Perovskite Solar Cells, 99%, 2g

1,3,5-Tris(1-phenyl-1H-benzimidazol-2-yl)benzene (TPBi) is an excellent hole-blocking and electron transfer material. It is extensively used in devices of OLEDs and perovskite solar cells, as well as a host material for both fluorescent and phosphorescent light-emitting systems because of the high electron mobility and the wide energy gaps.
