摘要

The rates of Ru (His33) cytochrome c electron-transfer (ET) reactions have been measured over a driving-force range of 0.59 to 1.89 eV. The driving-force dependence of Fe2+→ Ru3+ ET in RuL2 (im)(His33) cyt c [L= 2, 2'-bipyridine (bpy), 4, 4', 5, 5'-tetramethyl-2, 2'-bipyridine (4, 4', 5, 5'-(CH3) 4-bpy), 4, 4'-dimethyl-2, 2'-bipyridine (4, 4'-(CH3) 2-bpy), 4, 4'-bis (N- ethylcarbamoyl)-2, 2'-bipyridine (4, 4'-(CONH (C2H5)) 2-bpy), 1, 10-phenanthroline (phen) ...
