Title: Dibenzothiophene/terpyridine conjugated asymmetric electron transporters for high-efficiency and long-life green phosphorescent OLEDs

Abstract: A series of dibenzothiophene/terpyridine conjugated asymmetric electron-transporters named snTPys (n = 2, 3, 4) were developed. A green phosphorescent OLED with snTPy as an electron-transporter exhibited an external quantum efficiency of 24% at 1000 cdm-2 with a long operation lifetime at 50% of the initial luminance of 19,000 hrs at 1000 cd m-2.
