Abstract

Novel organic light-emitting diodes (OLEDs) using polymidy, fluorene-based cardo perylere polyimide (PFB5) were fabricated. EL properties of single-layer light-emitting diodes (LED) of indium-tin-oxide (ITO)/PFB5+/Al and ITO/PFB5+PBD/Al and multi-layer devices of ITO/PFB5/PBD/Al,ITO/PFB5/Alq/Al were characterized. In the pure PFB5 single layer device, the EL spectrum has a broad band and the peak wavelenght at 420nm, 450nm, and 545nm respectively. However, the EL emission fromthe single layer deviec of PFB5 blend PBD or multi-layer devices has the greatly narrow band and the peak wavelength at 545nm. Furthermore, the EL efficiency is improved significantly in these EL devices.
