文摘

A new pinwheel-like triazine molecule functionalized by three BMes₂(m-Ph) groups (B3T) has been synthesized and fully characterized. This molecule has been found to have a low LUMO (E_a = 3.25 eV) and a deep HOMO (6.73 eV) energy level with a high triplet energy level (3.07 eV) and is thus very promising as an electron transport material for phosphorescent OLEDs. Preliminary studies show that B3T is indeed a very effective electron transport material for OLEDs where the green phosphorescent compound Ir(ppy)₂(acac) is used as the emitter.
