Abstract
Organic materials and organic electroluminescent apparatuses using the same are provided. The structural general formula of the materials is shown below, wherein Ar is selected from residues of C6-C30 fused-ring aromatic hydrocarbons, Ar1 and Ar2 are each independently selected from the group consisting of hydrogen, C6-C24 aryl, and C6-C24 heterocyclic aryl, and n is an integer selected from 2 and 3. The present organic materials can be used as electron transport layers in the organic electroluminescent apparatuses.
