Claims16
An aromatic amine derivative comprising recurring units of the following general formula (1) and having a number average molecular weight of 250 to 100,000,
- wherein R1 is a substituted or unsubstituted monovalent hydrocarbon group or organooxy group,
- A and B each are independently a divalent group of the following general formula (2) or (3):
- wherein R2 to R11 each are independently hydrogen, a hydroxyl group, substituted or unsubstituted monovalent hydrocarbon group, organooxy group, acyl group or sulfonate group,
- m and n each are independently a positive number of at least 1, and the sum of m+n is 3 to 3,000.
An electroluminescent device comprising an anode, a cathode, and at least one electroluminescent organic layer interposed therebetween, wherein a luminescent material in said organic layer emits light upon application of a voltage between the anode and the cathode, and wherein an auxiliary carrier transporting layer which contains an aromatic amine derivative comprising recurring units of the following general formula (1) and having a number average molecular weight of 250 to 100,000 is formed between said anode and said organic layer
- wherein R1 is a substituted or unsubstituted monovalent hydrocarbon group or organooxy group,
- A and B each are independently a divalent group of the following general formula (2) or (3):
- wherein R2 to R11 each are independently hydrogen, a hydroxyl group, substituted or unsubstituted monovalent hydrocarbon group, organooxy group, acyl group or sulfonate group,
- m and n each are independently a positive number of at least 1, and the sum of m+n is 3 to 3,000.
