Benzo[b]naphtho[2,1-d]furan, 5-bromo-7-chloro-

Benzo[b]naphtho[2,1-d]furan, 5-bromo-7-chloro- (5-bromo-7-chloronaphtho[1,2-b]benzofuran) is a derivative of Dibenzofuran. Dibenzofuran based on electron-rich moiety 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. Dibenzofuran is also a suitable electron donor; therefore, compounds containing both dibenzofuran and TPA are not only thermally stable but also have relatively high HOMO energy levels, which can lower the energy barriers for hole transport, thereby enhancing hole mobility.
