Abstract
Dimer structures of pyrazoline derivatives were synthesized in order to obtain stable films and applied to electroluminescent (EL) devices as hole transport material. A device structure of [indium-tin-oxide (ITO)/hole transport layer (HTL)/emitting layer (EML)/MgIn] was employed. When pyrazoline dimer (PYR-D3) and tris(8-hydroxyquinolinate)aluminum ( Alq3) were used as HTL and EML, respectively, the EL device showed a maximum luminance of 12400 cd/m2 at 11 V and a maximum luminous efficiency of 1.5 lm/W at 250 cd/m2. This showed that pyrazoline dimers functioned well as hole transport layers.This publication has 10 references indexed in Scilit:
