europium and terbium to form luminescent complexes in water at neutral pH. When testing these unsaturated complexes as anion sensors with NO(3)(-), HPO(4)(2)(-), AMP, ADP, and ATP, a marked selectivity is observed for HPO(4)(2)(-) and ATP(4)(-) at pH = 7.0. The interaction of these anions with the complex was investigated by means of absorption and emission spectroscopies. With ATP(4)(-), ES-MS and (31)P
配体LH(2)由连接至氨基丁基链的两个联吡啶基羧酸盐片段组成,与euro和ter反应,在中性pH值的水中形成发光配合物。当测试这些不饱和配合物作为NO(3)(-),HPO(4)(2)(-),AMP,ADP和ATP的阴离子传感器时,对HPO(4)(2)(- )和ATP(4)(-)(pH = 7.0)。通过吸收和发射光谱法研究了这些阴离子与络合物的相互作用。使用ATP(4)(-),ES-MS和(31)P NMR实验揭示了[Ln.L.(ATP)](3)(-)三元物种的形成。
