CAS.530402-77-8 4-(4-Bromophenyl)dibenzothiophene

4- (4-bromophenyl) dibenzothiophene contains the core structure of dibenzothiophene and has good conjugation. This conjugated system can effectively enhance the light absorption and emission performance, which is an important characteristic of OLED luminescent materials. In addition, 4- (4-bromophenyl) dibenzothiophene can serve as an electron donor or acceptor, depending on its binding with other materials. Its electronic properties enable it to promote the recombination of electrons and holes in OLEDs, thereby improving luminous efficiency.
