碩士 === 靜宜大學 === 應用化學系 === 101 === We report herein the synthesis and characterization of the ruthenium dinuclear complexes with end-caping of pyridinedicarboxylate of terpyridine(2,2’:6’,2”-terpyridine) bridging with carbon-rich alkynyl and phenyl groups. These novel complexes are characterized by NMR, FT-IR, UV-vis and CV. Furthermore, the electrochemical behavior of the ruthenium complexes was show to be weakly dependent on the form of the systems with one irreversible and one eversible electrochemical redox waves in positive wave were observed (E1/2= 1.40 and 0.45 (irrev) for the complex with ethynyl-phenyl spacer and E1/2 1.57 and 0.38 (irrev) for the complex with ethynyl-2-nitrophenyl spacer), indicating a strong electronic interaction between two Ru metal centers.
