Abstract
Highly fluorescent polymeric LEDs (PLEDs) utilizing blue-emitting FB fluorene derivatives (FBF14 and FBPh4) blended with PVK are demonstrated. Significant red shift of the emission from blue to red can be achieved by increasing the concentration of FB in the blend. The origin of emission was attributed to electromer (or electroplex) formation. Addition of Carb9 in the blend enhanced the electromer (or electroplex) formation, and red- or white-emission device with high brightness (3440 cd/m2 for red; and 17368 cd/m2 for white) was obtained.
