Poly-(2,5-Thienylene Vinylene) (PTV) derivatives have been synthesised via the “dithiocarbamate precursor route” in good yield and satisfactory molecular weight. Structural characterisations of the conjugated PTV polymers reveal an optical band gap around 1.8 eV. Organic field effect transistors and organic based photovoltaic devices were made with the plain PTV, via a precursor approach. More specifically,...
A new synthetic route towards poly(para-phenylene vinylene) (PPV) and its derivatives has been investigated. In this route, a bis-dithiocarbamate monomer is polymerized towards a dithiocarbamate precursor polymer by the addition of a strong base (LDA). The corresponding conjugated polymer is obtained via a heat treatment of the precursor polymer. This dithiocarbamate (DTC) precursor route strikes...
New derivatives of poly(thienylene vinylene) (PTV), more specifically the 3,4-dichloro and 3,4-dibromo derivatives, have been synthesised. Their structural characterisation reveals a high molecular weight (>50000 Da) and an optical band gap of 1.55 eV. For comparison also the properties and behaviour in photovoltaic devices of a soluble poly(bisthienylene isothianaphthene) derivative is discussed...
