Abstract: A series of chrysene-based electron-transporters named BnPyPCs (n = 2, 3, 4) end-capped with two 3,5-di(pyridin-n- yl)phenyl moieties with high thermal and electrical stability were successfully developed. BnPyPCs showed Tm values greater than 390 ̊C and were used for highly efficient green phosphorescent OLEDs with maximum external quantum efficiency values greater than 20% and long operation lifetime at high brightness of approximately 11000 cd m–2 at a current density of 25 mA cm–2.
