AROMATIC AMINE DERIVATIVES AND PREPARATION METHOD, USES AND ORGANIC ELECTROLUMINESCENT DEVICES THEREOF
Abstract:
The present invention relates to the field of organic electroluminescent technology, particularly relates to an aromatic amine derivative, its preparation method, uses and organic electroluminescent devices. The technical aim of the present invention is to improve the film forming ability and the redox repeatability. The aromatic amine derivative has the structure of formula I, wherein, R1, R2, R3 and R4 each independently represent a hydrogen, a substituted or unsubstituted C1-C40 alkyl, a substituted or unsubstituted C1-C40 alkoxy, a substituted or unsubstituted C3-C40 cycloalkyl, a substituted or unsubstituted C6-C50 aryl group, a substituted or unsubstituted C3-C50 heteroaryl containing one or two heteroatoms selected from N, O and S, or a substituted or unsubstituted C10-C40 fused aryl group formed together with the phenyl group linked therewith; wherein, m, n, p and q each independently represent 0, 1, 2, 3, 4 or 5; the substituents are one or more groups selected from the group consisting of a halogen, a C1-C10 alkyl, a C1-C10 alkoxy, a C3-C20 cycloalkyl, a C6-C20 aryl group or a C4-C20 heteroaryl group. The present invention may be applied in organic electroluminescent devices.
