应用

It′s a star-shaped carbazole hole-transporting material popularly used in OLEDs as solution-processable fluorescent emitting host, or as electron-blocking layer for quantum-dot light-emitting diodes (QD-LEDs).
TCTA is widely used as a hole transport material in OLED and organic photovoltaic (OPV) devices. It possesses excellent hole injection and transport properties, helping to efficiently transport positive charges (holes) from the anode to the emitting layer.
