Redox- and Protonation-Induced Fluorescence Switch in a New Triphenylamine with Six Stable Active or Non-Active Forms

Quinton, C; Alain-Rizzo, V; Dumas-Verdes, C; Miomandre, F; Clavier, G; Audebert, P CHEMISTRY-A EUROPEAN JOURNAL 2015, 21, 2230-2240.

The synthesis, photophysical and electrochemical properties as well as theoretical calculation studies of a newly designed triphenylamine derivative are described. This original compound displays one neutral form, three oxidized forms, and two protonated forms with distinct photo-physical characteristics. The interplay of the emission with the protonation or the redox state (electrofluorochromism) has been explored and an on-off-on-off fluorescence switching was observed in the case of oxidation and an on-on-off fluorescence switching in the case of protonation.
