Novel four-pyridylbenzene-armed biphenyls as electron-transport materials for phosphorescent OLEDs
A series of four-pyridylbenzene-armed biphenyl derivatives were designed and synthesized as an electron-transport and exciton- and hole-block layer for the fac-tris(2-phenylpyridine)iridium (lr(PPy)3)-based green phosphorescent organic light-em
