Abstract:A novel anthracene derivative, disilanyl double-pillared bisanthracene ( Si DPBA), has been recently synthesized, which effectively functions as a bipolar carrier transport material in OLEDs. Its charge transport properties have been systemically investigated by band model and hopping model. Band structure calculations of Si DPBA show that the dispersions of the larger valence band and conduction band are comparable, which demonstrates that both electron and hole are favoured for transport, and that Si DPBA ha… Show more
