The first part of this thesis is devoted to the synthesis, purification and application of a series of indenopyrazine based polymers for their use in optoelectronic devices. The work focuses on the effect of alternating chain length on the degree of polymerisation, optical and charge carrier properties The next section studies the copolymerisation of indenopyrazine with dithiophene benzothiadiazole acceptor units and the effect substituents have on the planarity of the polymer backbone and the delocalisation of molecular orbitals and solar cell performance. The final part of this thesis investigates indenopyrazine based polymers as charge carrier materials in p-type transistors and probes the effect p-dopants have on the energy levels, charge carrier mobility and optical properties. The second part is the synthesis of the novel alkylidene-indenopyrazine monomer and probes the introduction of enforced planarity and finally the synthesis towards the novel the semiconductor indenopyrazinedithiophene.
