This thesis describes the incorporation of a flavin unit into a range of systems spanning photovoltaics and biomimetic self-assembly. The flavin unit is better known as a cofactor in a range of enzymes. However, the unique physical and self-assembly properties were exploited in this research programme to develop new systems with photovoltaic and biomimetic self-assembly applications.
In Chapter 1 a general introduction relating to flavins and photovoltaics is provided. In Chapter 2, the aim was to explore the effect of the addition of fullerene to a range of acceptors in the expectation of forming new acceptor materials with a wide range of LUMO energies. In Chapter 3, the aim was to investigate the effect of coupling a flavin unit to a naphthalenediimides (NDI) unit in the expectation of forming hybrid materials for solar energy conversion. Chapter 4 describes the formation of conjugated polymers featuring a flavin moiety, in the expectation that these materials will have photovoltaic properties. Chapter 5 describes the synthesis of push-pull flavin systems with pH dependent visisble light absorption characteristics. Finally Chapter 6 describes the synthesis of water soluble ammonium salts to furnish new micelle based systems with hydrogen bonding recognition properties.
