There is currently great interest in photochemical molecular devices (PMDs) which are capable of performing various useful functions such as the conversion of sunlight into electrical or chemical energy. Recent work with photovoltaic cells containing Ru(II)-2,2'-bipyridine dyes demonstrates that photoacctive transition metal complexes have real potential as PMDs, but progress in this area has been hindered by synthetic limitations. A primary objective of fundamental PMD research is the creation of relatively simple systems capable of efficient, long-lived photoinduced charge-separation (PICS).We intend to prepare novel chromophore-quencher (CQ) complexes containing highly stable Ru(IQ trans-bis(pdma) [pdma =1,2phenylenebis(dimethylarsine)] electron donor centres combined with pyrtdinium, Ru(II) or Re(D-based electron acceptor groups. Unlike most known CQ complexes, ours will exhibit solely axial metal-to-ligand charge-transfer excitations in the visible region of the electromagnetic spectrum. Judicious design of the redox and stereochemical properties is expected to lead to long-lived PICS excited states. Ugand changes will permit a high degree of tunability of the photoexatation properties of the chromophores, and selective substitutions of labile chloride ligands will also allow controlled structural extensions, rarely possible in existing CQ complexes. Sophisticated transient visible, infrared and Raman absorption spectroscopic measurements will be employed to characterize the excited-states formed within short timescales (micro/nanoseconds) following visible laser excitations.Keywords describing areas of proposal: Inorganic Chemistry, Synthesis, Photochemistry
