Fluorenylporphyrins functionalized by electrochromic ruthenium units as redox-triggered fluorescence switches

Two dyads containing tris-and tetrakis-meso-fluorenyl-substituted porphyrin and ethynylruthenium units, 1 and 2, were investigated by emission spectro-electrochemical (SEC) methods for their potential use as fluorescence switches. The ruthenium…
