Lanthanide-based luminescentprobes TPR1 and TPR2 were developed for the detection of hydrogenperoxide (H(2)O(2)) in living systems. The chemoselective reaction of these boronate-protected probes with H(2)O(2) resulted in an enhanced lanthanide sensitization and a 6-fold increase in luminescent intensity. TPR2 was utilized to measure the endogenous production of H(2)O(2) in RAW 264.7 macrophages using

innersphere with a dissociationconstant of 17 μM. Luminescence emission peak changes upon addition of anion to Eu(S-THP) show that there are two distinct binding events for phosphate and methylphosphate with dissociationconstants of 0.3 mM and 3.0 mM for phosphate and 0.6 mM and 9.8 mM for methyl phosphate. Eu(THPC) contains an appended carbostyril derivative as an antenna to sensitize Eu(III) luminescence
(1 S ,4 S ,7 S ,10 S )-1,4,7,10-四(2-羟丙基)-1,4,7,10-四氮杂环十二烷( S-THP )的Eu(III)络合物被研究作为生物相关阴离子的传感器。阴离子相互作用会导致 Eu(III) 配合物的发光发射光谱、1 H NMR 光谱以及配合物的 PARACEST 光谱发生变化(PARACEST = 顺磁性化学交换饱和转移)。Eu( S-THP)的直接激发光谱和发光寿命研究) 提供有关阴离子相互作用的形态和性质的信息,包括 pH 7.2 时的碳酸盐、醋酸盐、乳酸盐、柠檬酸盐、磷酸盐和甲基磷酸盐。数据与 Eu( S-THP ) 与醋酸盐、乳酸盐和碳酸盐的内球和外球复合物的形成一致。这些阴离子的解离常数较弱,范围为 19 至 38 mM。柠檬酸盐与 Eu ( S-THP ) 的结合主要是内球体,解离常数为 17 μM。向 Eu ( S-THP )添加阴离子后的
