The embodiment of the invention provides an aromatic amine derivative, and a preparation method, a use and an organic electroluminescent device thereof, and relates to the technical field of organic electroluminescence. The aromatic amine derivative is invented to improve the film forming ability and the redox repetition stability. The structural general formula I of the aromatic amine derivative is shown in the specification; and in the formula I, R1, R2, R3 and R4 respectively independently represent hydrogen, substituted or unsubstituted C1-C40 alkyl groups, substituted or unsubstituted C1-C40 alkyloxy groups, substituted or unsubstituted C3-C40 cycloalkyl groups, substituted or unsubstituted C6-C50 aryl groups, substituted or unsubstituted C3-C50 heteroaryl groups containing one or two selected from hetero atoms of N, O or S, or substituted or unsubstituted C10-C40 fused aryl groups, m, n, p and q respectively independently represent 0, 1, 2, 3, 4 or 5, and substituent can be one or more groups selected from halogens, C1-C10 alkyl groups, C1-C10 alkyloxy groups, C3-C20 cycloalkyl groups, C6-C20 aryl groups or C4-C20 heteroaryl groups. The aromatic amine derivative can be used in the organic electroluminescent device. |
