| Summary: | 碩士 === 輔仁大學 === 化學系 === 98 === The thesis is focused on the synthesis and characterization of series of mono-ruthenium complexes, and a tri-metal complex, including pyridyl and rutheniumammine moieties, cis-[Ru(NH3)4(PP)2]2+ (PP = 4-phenphylpyridine, 4-acetylpyridine, and pyrazine), and cis-[Ru-(NH3)4(pz)2{Ru(NH3)5}2]6+, trying to describe the electronic coupling between Ru(II)-dπ and PP-π*, and between Ru(II)-π and PP-π* combinational orbitals. For cis-[Ru(NH3)4(PP)2]2+ series, the strong coupling element (6,000 cm-1 ~ 9,000 cm-1) between Ru(II)-dπ and PP-π* combinational orbitals were described by the perturbation argument. Likewise, we found in a tri-metal complex, which has 90 mV difference between two E1/2 (RuIII/II) of terminal ruthenium moieties and indicated that the end-to-end coupling ranged between 600 cm-1 ~1,000 cm-1.
