The present invention provides a sulphone-contained compound, an organic electroluminescence device using same, and a fabrication method thereof. The structural formula (I) of the sulphone-contained compound is expressed above. In the formula (I), R is a group which can connect three or more sulfur-oxygen fluorine units, R1, R2, and R3 are the alkyl chain, the aromatic nucleus group, or the heterocyclic group. The sulphone-contained compound of the present invention combines the three or more sulfur-oxygen fluorine units together by using a bridging unit, to form a novel sulphone-contained compound of a star-shaped molecular structure, and this novel compound not only has the electron affinity and the electronic transmission performance of the sulfur-oxygen fluorine, but also has the spatial characteristic of the star-shaped molecule; moreover, the bridging unit can further provide a hole transport capability or an electronic transmission capability, and enables the capability to be used in the light emitting layer or the electronic transmission layer of the organic electroluminescence device, thereby effectively improving the efficiency and service life of the organic electroluminescence device. |
