A new synthetic procedure for the efficient preparation of dinuclear ruthenium(II) polypyridyl complexes is reported. The compounds synthesised are [(bpy)2Ru(BPBT)Ru(bpy)2] (PF6)2and [(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. (C) 2000 Published by Elsevier Science S.A.
