We consider the present understanding of the operation of light-emitting diodes which use conjugated polymers for both charge transport and emission. We highlight the improvement to the electroluminescence efficiency that can be produced by the use of two polymer layers selected so that the heterojunction between the two layers is able to confine charge and thus bring about electron-hole capture to generate excitons at this interface. We present results for devices made with the heterojunction formed between a layer of poly(p-phenylene vinylene), PPV, and nitrile substituted PPV`s.
