This thesis is concerned with the electrochemical behaviour of mono- and polynuclear ruthenium complexes containing redox-active dioxolene ligands. Chapter One provides a general introduction to the relevant issues concerning the work reported in the rest of the thesis; in particular electron transfer processes in ruthenium complexes, and the coordination chemistry of dioxolene and crown thioether (or thiacrown) ligands. Chapter Two describes the synthesis of a series of mononuclear ruthenium (II) complexes incorporating both tetradentate thiacrown and bidentate dioxolene ligands. The electronic and spectroscopic behaviour of the complexes is discussed, and compared with analogous ruthenium (II) bipyridine complexes from the literature. Chapter Three describes the synthesis and behaviour of several polynuclear rutheniumthiacrown complexes, bridged by polydioxolene ligands. The electrochemical and spectroscopic behaviour of the complexes is again discussed. The fabrication of a solidstate electrochromic device incorporating a trinuclear complex is reported. Chapter Four discusses the synthesis and characterisation of a series of polynucleating bridging ligands. The ligands consist of two or three dioxolene units, linked by vinyl bridges and containing a range of aromatic spacer units. The coordination of these ligands to ruthenium centres and the behaviour of resultant complexes is also described.
