摘要

A series of 3(6),9'-linked oligocarbazoles with large triplet energies and morphological stability are reported as host materials for electrophosphorescence. In such oligocarbazoles, the triplet excitation is confined within one carbazole unit, leading to a new molecular design strategy for large-triplet-energy and high morphological stability hosts. Using these hosts, efficient blue phosphorescent OLEDs having efficiencies up to 15%, 31 cd/A and 28 Im/W are demonstrated.
