Original new fluorescent and electroactive compounds have been prepared, where the fluorescent moiety is a chloroalkoxy-s-tetrazine. Besides the tetrazine, several of these compounds possess a second active group, electroactive or able to absorb light at a lower wavelength. The electrochemical properties and photophysical properties of these bichromophoric compounds have been investigated, especially focusing on the occurrence of energy or electron transfer to the tetrazine. In one case, where the primary absorber is a naphthalimide, a quasi-complete energy transfer, followed by the tetrazine fluorescence, is observed. This allows the preparation of remarkable transparent solutions displaying a yellow fluorescence.
