AROMATIC DIAMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

摘要

Disclosed is an aromatic diamine derivative represented by the general formula (I) below, which has a chrysene structure wherein a phenyl group having a substituted or unsubstituted silyl group is a substituent of an amino group. Also disclosed is an organic electroluminescent device wherein an organic thin film composed of one or more layers including at least a light-emitting layer is interposed between a cathode and an anode. At least one layer of the organic thin film contains the aromatic diamine derivative by itself or as a component of a mixture. The organic electroluminescent device has long life and high luminous efficiency. (In the formula, R1-R10 independently represent a hydrogen atom, an alkyl group having 1-50 carbon atoms or the like; R11 represents a substituted or unsubstituted alkyl group having 1-50 carbon atoms or the like; at least one of A, B and C represents a substituted or unsubstituted silyl group, and the others respectively represent a hydrogen atom, a substituted or unsubstituted alkyl group having 1-50 carbon atoms or the like; and a, b, c and d independently represent an integer of 1-5.)
