CAS.669773-34-6 4,6-Dibromodibenzothiophene

This compound has excellent electronic transport properties. The thiophene ring in its structure can effectively promote the movement of electrons, making it suitable for use as an electron transport material (ETM), thereby improving the overall charge injection efficiency of OLED devices. In addition, the energy level structure of 4,6-dibromodibenzothiophene can match the luminescent layer and hole transport layer in OLEDs. This matching helps to reduce energy barriers between electrons and holes, enhance charge recombination efficiency, and thus improve luminescence performance.
