Used as a boronic ester intermediate containing a dibenzothiophene core for advanced organic synthesis. It is mainly applied in Suzuki-Miyaura cross-coupling reactions for the preparation of conjugated organic semiconductor materials, OLED functional materials, fluorescent materials, and other optoelectronic compounds. The pinacol boronate group provides high reactivity and stability for carbon-carbon bond formation.
