We have developed a new ratiometric fluorescent chemosensor 1 based on xanthine alkaloid theophylline moiety for the detection of dihydrogen phosphate and ATP. The chemosensor 1 selectively recognizes tetrabutylammonium dihydrogen phosphate in CH(3)CN/H(2)O (9:1) by exhibiting a significant decrease in the emission of naphthalene and its sensing properties regarding ATP and other related phosphate species were evaluated. The anion binding properties of 1 were evaluated by (1)H NMR, UV-vis, and fluorescence spectroscopic methods.
我们开发了一种新的基于黄嘌呤生物碱茶碱部分的比率荧光化学传感器 1，用于检测磷酸二氢盐和 ATP。该化学传感器 1 在 CH(3)CN/H(2)O（9:1）中选择性地识别四丁基磷酸二氢盐，通过显示萘的发射显著降低，并且评估了其关于 ATP 和其他相关磷酸盐物种的传感性能。通过 (1)H NMR、UV-vis 和荧光光谱法评估了 1 的阴离子结合特性。
