CAS.111296-91-4 5H,12H-Indolo[3,2-a]carbazole

Due to its excellent conjugated system and high HOMO energy level, 5,12-dihydroindolo [3,2-a] carbazole is particularly suitable for the synthesis of hole transport layer (HTL) materials. It can effectively transport holes and reduce the recombination loss of electrons and holes. The high thermal stability of its multi ring structure can ensure the stable operation of OLED devices under high temperature conditions and extend the lifespan of the devices. In addition, the intermediate can be further chemically modified for the development of blue or green emitting materials. By coupling with other conjugated units, the emission wavelength and energy level matching can be precisely adjusted to optimize the luminescence efficiency of the device.
