3-Bromo-1-chlorodibenzofuran

3-Bromo-1-chlorodibenzofuran is a chlorinated or brominated derivative of dibenzofuran. Dibenzofuran has been widely used for designing HTMs and host materials because of its high triplet energy and thermal stability, which make substituted dibenzofurans ideal materials for use in organic optoelectronic devices, including OLEDs, field-effect transistors, and photovoltaic cells.
