چکیده
A new synthetic procedure for the efficient preparation of dinuclear ruthenium(II) polypyridyl complexes is reported. The compounds synthesized are [(bpy)2Ru(BPBT)Ru(bpy)2](PF6)2 and [(bpy)2Ru(BPZBT)Ru(bpy)2](PF6)2. (bpy = 2,2’bipyridine; H2BPBT = 5,5’-bis(pyridin-2-yl)-3,3’-bis(1,2,4-triazole); H2BPZBT = 5,5’bis(pyrazin-2-yl)-3,3’-bis(1,2,4-triazole). Electrochemical experiments show that the two dinuclear systems investigated exhibit pH switchable intercomponent interactions. Keywords; Ruthenium complexes, coupling reactions, electrochemistry, dinuclear complexes.
