White polymer light-emitting diodes based on dibenzo-24-crown-8 decorated orange-emitting iridium complexes

Both yellow and white PLEDs are fabricated with a simple single-emission-layer configuration based on dibenzo-24-crown-8 unit decorated iridium complexes. The WPLED combination of complex 2 with FIrpic exhibits a CIE coordinates of (0.33, 0.39), which is very close to the pure white color.167
