Dibenzothiophene sulfone

white to yellow crystalline powder

Dibenzothiophene sulfone serves as a key structural unit and precursor for designing asymmetric dibenzothiophene-S,S-dioxides, high-mobility blue-emissive organic semiconductors, and donor/acceptor-type TADF compounds[1][2][3]. Dibenzothiophene sulfone is employed as a starting material undergoing initial bromination followed by Suzuki coupling with 2-naphthaleneboronic acids to synthesize high-mobility blue-emissive organic semiconductors[2].
