Additional Materials and Methods Synthesis of [Ru(bpy) 2 (bpy-no)](pf 6 ) 2 The synthesis process of the [Ru(bpy) 2 (bpy-no)](pf 6 ) 2 complex was conducted in the dark or under dim red light due its light sensitivity. 200 mg (0.38 mmol) of [Ru(bpy) 2 Cl 2 ] 2H 2 O were first dissolved in 30 ml of EtOH. 130mg (0.76 mmol) of AgNO 3 was subsequently added to the resulting solution and the mixture was refluxed for around 30 min (The deposited AgCl was separated by filtration). 20 ml of triethyl orthoformate (dehydrating agent) was then added to the resulting solution and the mixture was heated for 20-30 min at 50-60 C while continuously stirring.meanwhile, bipyridine-n-oxide ligand (72.3 mg, 0.42 mmol) was dissolved separately in 10 ml of EtOH- triethyl orthoformate (3/2, volume) mixture and warmed for 20-30 min at 50-60 C again while continuously stirring. The two solution mixtures were then mixed, stirred for 1 hour at 80 C and reduced to around 1/3 of its volume by by rotor evaporation. In order to precipitate [Ru(bpy) 2 (bpy-no)](pf 6 ) 2, (131 mg, 0.8 mmol) of NH 4 PF 6 was dissolved in 1 ml of the preheated mixture of the EtOH- triethyl orthoformate (3/2, volume),added in solution and kept in the refrigerator at -5 C Crystals were formed overnight, filtered and washed with small amounts of cold ethanol. Due to its light sensitivity, the obtained crystals were stored in the dark during its characterization through mass spectroscopy,nmr and EPR. The EPR spectrum of the resulting [Ru(bpy) 2 (bpy-no)](pf 6 ) 2 solution in ethanol is shown in Figure S1. The properties of this compound are be described in a separate manuscript currently in preparation. S2
