“…This behavior effected all three phosphorus signals, thus indicating that each phosphate unit of ATP is located close to the paramagnetic europium(III) center. A similar observation by Ziessel and co‐workers34 supports the binding of ATP. A tentative structure for the interaction of ATP with [EuL 2 Cl 3 ] can be proposed (Figure 13).…”

Phenanthroline-based hexadentate ligands L(1) and L(2) bearing two achiral semicarbazone or two chiral imine moieties as well as the respective mononuclear complexes incorporating various lanthanide ions, such as La(III), Eu(III), Tb(III), Lu(III), and Y(III) metal ions, were synthesized, and the crystal structures of [ML(1)Cl(3)] (M=La(III), Eu(III), Tb(III), Lu(III), or Y(III)) complexes were determined. Solvent or water molecules act as coligands for the rare-earth metals in addition to halide anions. The big Ln(III) ion exhibits a coordination number (CN) of 10, whereas the corresponding Eu(III), Tb(III), Lu(III), and Y(III) centers with smaller ionic radii show CN=9. Complexes of L(2), namely [ML(2)Cl(3)] (M=Eu(III), Tb(III), Lu(III), or Y(III)) ions could also be prepared. Only the complex of Eu(III) showed red luminescence, whereas all the others were nonluminescent. The emission properties of the Eu derivative can be applied as a photophysical signal for sensing various anions. The addition of phosphate anions leads to a unique change in the luminescence behavior. As a case study, the quenching behavior of adenosine-5'-triphosphate (ATP) was investigated at physiological pH value in an aqueous solvent. A specificity of the sensor for ATP relative to adenosine-5'-diphosphate (ADP) and adenosine-5'-monophosphate (AMP) was found. (31)P NMR spectroscopic studies revealed the formation of a [EuL(2)(ATP)] coordination species.

“…In preliminary studies, both the absorption and emission of complexes 594 were observed to undergo changes upon the addition of inorganic phosphate or ATP in aqueous media at pH 7.0 (Tris/HClO 4 buffer). 651 No spectral changes were observed upon the addition of AMP or ADP. Consistent with what was seen with system 593 above, spectral analysis supported the displacement of water from the inner coordination sphere of the lanthanide.…”

“…If the amount of anion is maintained at or below two equivalents, the systems are appropriate for anion detection in noncoordinating solvents such as acetonitrile. To allow anion detection in protic solvents, 9 was developed [79]. This ligand is hydrophilic, due to the carboxylate moieties, and heptadentate.…”
