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 (Ea = 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.
