Silicon-substitued PPV for LED preparation

The photoluminescence and electroluminescence of a novel kind of soluble poly(phenylenevinylene) containing silyloxy groups (PPV-OSi) have been studied PL is not detectable in the solid state for the pure material while is present in solution and in thin film of blend with polystyrene and polymethylmethacrilate. Electroluminescence was found only in the case of LEDs formed with blends.
