The high electron affinity (2.88−2.97 eV), robust thermal stability, suitable solution processability, and weak-to-moderate intrinsic electroluminescence of the polymers make them attractive for use as electrontransport materials in organic LEDs. Initial use of the polymers as the electrontransport materials in bilayer poly(2-methoxy-5-(2‘-ethylhexyloxy)-1,4-phenylenevinylene) (MEH−PPV) LEDs showed
