[Cr(ttpy)2]3+ as a multi-electron reservoir for photoinduced charge accumulation
Résumé
Under visible light irradiation [Cr(ttpy)2]3+ can be reduced twice by a tertiary amine; the photoreduction processes are accelerated in the presence of [Ru(bpy) 3 ] 2+ acting as an antenna thanks to an efficient electron transfer reaction from [Ru(bpy) 3 ] 2+* to [Cr(ttpy) 2 ] 3+ .
