Redox and Spectroscopic Properties of Ru dpq PtCl2 3 PF

SUPRAMOLECULAR COMPLEXES COUPLING Ru(II) POLYAZINE LIGHT ABSORBERS TO REACTIVE Pd(II) METAL CENTERS 

In the course of constructing molecules for solar energy conversion schemes, some attention has been given to polynuclear systems that combine ruthenium polypyridyl LAs to catalytically active Pd(II) centers. The systems use rigid and fiexible spacers that provide electronic coupling between the ruthenium and palladium centers.  

The electronic absorption spectra of the polyazine-bridged Ru(ll)-Pd(II) complexes show the typical ligand-based n n transitions in the UV and
