Femtosecond time‐resolved absorption revealed the formation of charged‐separated [ClPt III {C ∧ N ∧ N(PhMV +⋅ )}] species (left) with a forward rate constant of about 10 12 s −1 , which is more rapid than that of the back electron‐transfer process ( k −1 =1.6×10 9 s −1 ). Similar slower back ET reaction than forward light‐induced ET reaction of [Pt(MV‐bpy)(CCPh) 2 ](PF 6 ) 2 (right) has been observed. MV=methyl viologen.
