pyridoindole-type hostmaterials for blue phosphorescentorganiclight-emittingdiodes (PHOLEDs) was investigated by synthesizing three pyridoindole derivatives modified with dibenzofuran, dibenzothiophene, and 9-phenylcarbazole. The 9-phenylcarbazole moiety was better than dibenzofuran or dibenzothiophene to manage the energy levels and charge-transportproperties of the pyridoindole-derived hostmaterials. The
