Abstract

original image

The in situ assembly of organic nanowires within a conjugated polymer matrix yields blended emitting layers that are used in polymer light-emitting diodes (PLEDs). These PLEDs show significant enhancements in luminous efficiency and external quantum efficiency. The figure shows the structures of the materials used in the devices and the morphology of the organic nanowires.
