Abstract: 1,3-Diphenyl-5-dimethylaminophenyl-pyrazoline was successful to use as a hole transport layer in a EL device which was composed with the following configuration: ITO/DPDMP (40 nm)/PTT (40 nm)/Alq(40 nm)/Al. A green light with high purity from the terbium complex in the device has been observed.

Key words: pyrazoline derivatives, hole transport layer materials, electroluminescence
