New dyes based on BODIPY and tetrazine fluorophores con-nected through a phenyl spacer have been synthesized and their absorption, emission and electrochemical properties characterized. BODIPY can be reversibly oxidized into a stable cation radical whereas tetrazine can be reduced to a stable anion radical. The electrochemical and absorption studies demonstrate that both fluorophores behave indepen-dently. The bichromophoric compounds show an expected very weak emission by the BODIPY core that is quenched by the phenoxytetrazine mainly through energy transfer. DFT calculations and spectroelectrochemistry experiments dem-onstrate that photoinduced electron transfer and energy transfer remain possible when the tetrazine moiety is re-duced electrochemically, which prevents switching on of the fluorescence of the BODIPY unit.
