Abstract
Interaction between Rose Bengal (RB) and an iron arene complex [Irg(+)] was studied by steady state and laser flash photolysis experiments. The contribution of static fluorescence quenching is evidenced by time resolved fluorescence experiments and can be explained by the occurrence of a ground state complex between RB and Irg(+). After light absorption by RB, the singlet state of RB is intercepted within the RB/Irg(+) pair, leading to semi-oxidised RB and a 19e iron arene complex.
