TCTA, HTL and HIL material in LEDs and perovskite solar cells
Popular host material for green, red and white PhOLEDs
Having three carbazole units as the pendants and triarylamine at the core, tris(4-carbazoyl-9-ylphenyl)amine (TCTA) is electron-rich. As a result, it is widely used as a hole-transport and hole-injection material in light-emitting diodes and perovskite solar cells. With low electron mobility, TCTA has also been used as exciton/electron blocking layer materials because of its high lying LUMO energy level (LUMO = 2.4 eV).
TCTA is also a very popular phosphorescent host material due to its large band gap (Eg = 3.4 eV) for green, red and white phosphorescent organic light-emitting diodes (PhOLEDs).
