This paper describes the use of TIRF microscopy coupled to electrochemistry to investigate the electrofluorochromic properties of a new bipyidine–phenanthroline ruthenium complex. A reversible electrochemical modulation of luminescence is observed when applying potential steps between the reduced emitting state and the oxidized non emitting one. Variations of intensity and lifetimes along the potential steps are analyzed to understand the mechanism of this switch. It is shown that a quenching mechanism occurs upon electrooxidation that accounts for the fast luminescence switch process.
