1,3,4-oxadiazole containing silanes as novel hosts for blue phosphorescent organic light emitting diodes

Five rigid oxadiazole (OXD) containing silanes, denoted 1-5, have been developed with high morphological stability. Disruption of the π-aromatic conjugation by introduction of Si atoms leads to a large band gap and high triplet energy. Among the OXDs we s
