Electroluminescent polymers have attracted much attention recently due to their application in light emitting devices (LEDs) since the first report of poly(p-phenylenevinylene) (PPV) based LEDs by the Cambridge group. A Electroluminescent polymers have attracted much attention due to application in light- emitting devices (LEDs). A wide range of conjugated polymers have been exploited as the emissive and/or charge transporting materials, such as PPV and its derivatives, poly(p-phenylene)s, and polythiophenes. Currently, the major interest in developing light-emitting polymeric materials is focused on those with high photoluminescent quantum efficiency, good processability and long operating lifetime. Among the PPV derivatives, the most commonly utilized materials for polymer LEDs, investigated so far, the silyl substituted PPVs are quite attractive due to their extremely high PL efficiencies compared to PPV or alkoxy substituted PPVs. In addition, silicon- contai!
ning PPV polymers have demonstrated good solubility and uniform film morphology without any crystalline features as films. Here we present a very convenient synthesis of a new PPV derivative, i.e., poly(2,5-bisdecyldimethylsilyl-1,4-phenylenevinylene) (BDDMS-PPV), through introducing two silyl groups as the substituents on the phenylene ring.
