Abstract
New bimetallic and polymetallic ruthhenium and iron complexes with bridging bipyridines have been synthesized and characterized by NMR, IR, electrochemistry, and UV-Vis spectroscopy. These complexes are: Rc(bipy)2Rc, Rc(bipy)2,Fc, and Ru(bipy-Fc2)3, where Rc = ruthenocene, Fc = ferrocene, and bipy = 2,2-bipyridine. The electrochemical behavior of the complexes reveal strong electronic communication between ruthenium and iron transmitted through the bipyridine bridges. These can be used as building blocks for the design of luminescent and redox-reactive species containing a higher number of metal centers. The complexes as well as analogs can prove useful as antenna components for photosensitization processes (including electron or hole ejection on semiconductors), luminescence probes, and multi-electron photocatalysis.
