Tetrazine-based electrofluorochromic windows: Modulation of the fluorescencethrough applied potential

摘要

A series of new electrofluorescent switches was prepared using electroactive fluorescent tetrazines, anoriginal family of molecules featuring both highly stable reduced anion-radicals and fluorescence inthe neutral state. The cells were prepared with four layers: the tetrazine polymer film, a photo curedpolymer electrolyte film, and two indium-tin oxide films as the two contact electrodes. When externallybiased, the fluorescence of the tetrazine fluorophore can be switched on and off reversibly, according toits redox state through scanning the potential between two transparent ITO electrodes. Electrochromismof a tetrazine containing conducting polymer has also been examined.
