The O2 ( - ) . - production efficiency of 1 - ( I ( - ) ) 10 was confirmed by using an O2 ( - ) . - reactive bis ( 2 , 4 - dinitrobenzenesulfonyl ) tetrafluorofluorescein probe and correlated to the photoinduced electron - transfer event going from iodide anions to ( 3 ) C60 * [ > M ( C3N6 ( + ) C3 ) 2 ] leading to C60 ( - ) . [ > M ( C3N6 ( + ) C3 ) 2 ] .
