【 摘 要 】

Organic materials offer key advantages over their inorganic counterparts for photovoltaics due to the ability to easily tune the physical properties and develop cheaper, more flexible, photovoltaic devices. This thesis describes the synthesis and characterisation of a variety of compounds from small-molecule to supramolecular and polymeric systems with the potential to be used in organic electronics. Herein is described an optimised synthetic route for the synthesis of two flavins and the synthesis and characterisation of a novel flavin and fluorene polymer. Also described is the synthesis of two novel rotaxane structures with the potential for use in organic field effect transistors. The synthesis of a novel polymer incorporating the naphthalene diimide moiety and a P3HT functionality utilising click methodology is also described. Finally the synthesis of a thiophene based star shaped molecule as electron transporting material is also described along with a flavin based organic dye for use in dye-sensitised solar cells.
