英文摘要：

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.
