Abstract: A new bipolar phosphorescence host material carbostyril derivative 3-(4-(9H-carbazol-9-yl)phenyl)-1-methyl-4-phenylquinolin-2(1H)-one was designed and synthesized.Through theoretical calculations we found that the HOMO and LUMO obitals respectively localed in carbazole group and carbostyril group,that imply this compound is a good bipolar material.The compound phosphorescence emission is 515 nm(2.41 eV),meet the basic requirement of green phosphorescence host material(>2.40 eV).TGA and DSC results show the compound has high thermal stabilities,the decomposition temperature and glass transition temperature are 312 ℃ and 105 ℃ respectively.The results show that the new compound is a potential green phosphorescence host material with bipolar feature.

Key words: OLEDs, bipolar green phosphorescence host material, carbostyril derivatives
