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