Organic electronics is a rapidly developing field of both science and technology. Semiconducting conjugated polymers are performing an important role in the progression of optical electronic device applications. Photoluminescent and electroluminescent conjugated polymers have made
profound scientific and technological developments in a wide range of light-
emitting applications. This thesis deals with the design, synthesis and study of a novel class of 1-functionalised dibenzothiophene-S,S-dioxide monomers and then uses them to synthesise the first novel soluble 1-
functionalised dibenzothiophene-S,S -dioxide homopolymers, and co-polymers with fluorene units.
A series of novel 1-(alkoxy, alkylthio, alkyl sulfonyl) -dibenzothiophene-S,S-
dioxide onomers (Br2S-R) (I) with various solubilising alkyl chains (linear or branched) have been synthesised and fully characterised by 1H and 13C NMR spectroscopy and mass spectrometry.
