Light emitting diode devices prepared from poly(phenylenevinylene) grafted with poly(ethylene imine) show blue shifted spectra (λ(max)≃475- 490nm) proportional to the ratio of the grafted to ungrafted segmers and significantly (up to sevenfold) improved lifetimes; further coordination of transition metals led to increased electroluminescence intensity.
