Europium 2-benzofuranoate: Synthesis and use for bioimaging

Abstract Europium 2-benzofuranoate Eu(BFC) 3 (H 2 O) 3 was successfully used for bioimaging in cellulo due to the combination of high solubility and high luminescence intensity in solution. It was possible due to the purposeful variation of the aromatic core of carboxylate anion.
