Abstract

The synthesis and properties of a single copolymer incorporating well-separated blue, green, and red chromophores on a single conjugated polymer backbone are reported. This copolymer is shown to have CIE coordinates of (0.35,0.34) and a luminance efficiency of 6.2 cd A–1. The color coordinates of the resulting white-light emission remained extremely stable over a wide range of driving voltages.
