Abstract

Photoinduced electron-transfer reactions of [(tpy) RuII (tpy-tpy) CoIII (tpy)] 5+(tpy= 2, 2': 6', 2''- terpyridine and tpy-tpy= 6', 6''-bis (2-pyridyl)-2, 2': 4', 4'': 2'', 2'''-quarterpyridyne),[(tpy) RuII (tpy-ph-tpy) CoIII (tpy)] 5+(tpy-ph-tpy= 1, 4-bis [2, 2': 6', 2''-terpyridine-4'-yl] benzene), and [(bpy) 2RuII (tpphz) CoIII (bpy) 2] 5+(bpy= 2, 2'-bipyridine, and tpphz= tetrapyrido [3, 2-a: 2', 3'-c: 3'', 2''-h:: 2''', 3'''-j] phenazine) were studied in the range 140-298 K by means of ...
