Electron-, proton-, and photon-induced spectroscopic changes in chromophore-quencher tricarbonyl(2,2′-Bipyridine)rhenium(I) complexes with 4,4′-azobis(pyridine)

We report in this work the synthesis and characterization of new mono- and dinuclear complexes of formulas: [Re(bpy)(CO)3(4,4′-azpy)] (CF3SO3), 1 (bpy = 2,2′-bipyridine, 4,4′-azpy = 4,4′-azobis(pyridine)); [(bpy)(CO)3Re(4,4′-azpy) Ru(NH3)5](PF6)3.CH 3CN•6H2O, 2 and the heterodinuclear species [(bpy)...
