    <title language="eng">Five-, four- and three-dentate Europium chelates for anion sensing and their applicability to enzymatic dephosphorylation reactions</title>
    <abstract language="eng">The design of anion-sensitive probes with sufficient sensitivity and selectivity is a demanding task in analytical sciences and chemical sensor technology. The reversible binding of Anions to lanthanide centers is a possible approach for the development of molecular anion sensors, as reversibility is a prerequisite for continuous sensing and monitoring of enzymatic reactions. Some anion species lead to a strong increase of luminescence intensities and lifetimes by the replacement of luminescence quenching water molecules, though the selectivity of the luminescence response is still a major problem. We synthesized a series of positively charged pyridyl-based multidentate europium complexes (five-, four- and three dentate) including sensitizing chromophores and studied their luminescence intensity and lifetime responses to different polyphosphates, pyrophosphate, phosphate anions, and carboxyanions.&#13;
The results revealed that the number and symmetry of the binding sites have a significant impact on the response. The five-dentate complex was used for the real-time monitoring of the activity of the ATP hydrolyzing enzyme apyrase.</abstract>
