Electrochemistry coupled to fluorescence spectroscopy: a new versatile approach

Perylenediimide derivatives in new donor–acceptor dyads

“…Indeed, intramolecular PET would not be possible anymore as TTF loses its donating character upon oxidation. Experiments of emission fluorescence measurements coupled to electrochemistry were carried out at controlled potentials [19]. After applying an oxidation potential of +0.85 V where the TTF +• -PDI species must be predominant, surprisingly the fluorescence emission of the PDI part was not recovered.…”

Tetrazine-based electrofluorochromic windows: Modulation of the fluorescence through applied potential

“…However, there are few reports of direct fluorescence modulation through the applied electrochemical potential to the fluorophore, and most of the time the fluorogenic moietic itself is not directly involved in the electron transfer [2]. Up to now, there have been only three records where the fluorescence [3,4] of a molecule can be switched on and off by performing the redox chemistry on the fluorescent molecule itself, and only Levillain et al [4], and us reported that the transformation was only one outersphere single electron transfer leading to the ion-radical.…”

Electrofluorochromic Detection of Cyanide Anions Using a Nanoporous Polymer Electrode and the Detection Mechanism

“…1 After dissolution of all the compounds, Na 2 CO 3 aqueous solution (2 m, 6 mL) was added, and the mixture was degassed.…”

“…[1] A few types of electrofluorochromic (EFC) materials were reported in the following few years, [2] but the utilization of the EFC functionalities of the materials in various fields was sparsely explored. The first report on electrochemically switchable intrinsic fluorophores appeared in 2004.…”
