A Heterometallic Protocol for Turn-on Fluorescence. Synthesis, Structure, and Luminescence Behavior of a Diruthenium(III)–Magnesium(II) Complex Decorated with Four Pyrenecarboxylates
A new heterometallic diruthenium(III)–magnesium(II) complex functionalized with four pyrenecarboxylate fluorophores <b>1</b> has been synthesized and structurally characterized. Fluorescence from the pyrene moieties in <b>1</b> was nearly completely quenched in CH<sub>2</sub>Cl<sub>2</sub> (>98%), but turn-on fluorescence was successfully observed after regioselective substitution of the carboxylates bridging the heterometallic Ru(III)···Mg(II) sites.
