摘要：

A new synthetic procedure for the efficient preparation of dinuclear ruthenium(II) polypyridyl complexes is reported. The compounds synthesised rue [(bpy)(2)Ru(BPBT)Ru(bpy)(2)] (PF6)(2) and [(bpy)(2)Ru(BPZBT)Ru(bpy)(2)](PF6)(2) (bpy = 2,2'-bipyridine; H2BPBT = 5,5'-bis(pyridin-2-yl)-3,3'-bis(1,2,4-triazole); H(2)BPZBT = 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.
