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.

Parasitic optical absorption is one of the root causes of the moderate efficiency of metal halide perovskite solar cells (PSCs) with an opaque substrate configuration. Here, we investigate the reduction of these optical losses by using thin (7-10 nm), undoped

Inter- and intramolecular charge-transfer processes are combined using an exciplex-forming host and a thermally activated delayed fluorescent dopant, for fabricating efficient fluorescent organic light-emitting diodes along with the reduced efficiency roll-off at high current densities. Extra conversion on the host
