Synthesis and comparative anion binding profiles of two di-aqua Eu(III) complexes.
Two di-aqua Eu(iii) complexes of heptadentate ligands are reported that show differing reactivity profiles towards various anions; a cationic complex with two azaxanthone moieties exhibits pronounced selectivity towards bicarbonate with an affinity constant, logK = 2.65 (295 K, 0.1 M NaCl).
