active dansyl groups. The studies for the interaction of the synthesised compounds with various mental ions (Li+, Na+, K+, Ag+, Mg2+, Ca2+, Ba2+, Pb2+, Zn2+, Co2+, Cd2+, Hg2+, Ni2+, Cu2+, Mn2+, Cr3+, Al3+, Fe3+) were performed by fluorescence titration, Job’s plot, ESI-MS and DFT calculations. The results showed that the sensors 1a–1c displayed selective recognition for Cu2+ and Fe3+ ions and formed stoichiometry
摘要 在这项工作中,我们合成并表征了三种含有光学活性丹酰基的新型荧光大环传感器。合成化合物与各种金属离子(Li+、Na+、K+、Ag+、Mg2+、Ca2+、Ba2+、Pb2+、Zn2+、Co2+、Cd2+、Hg2+、Ni2+、Cu2+、Mn2+、Cr3+、Al3+、Fe3+)相互作用的研究通过荧光滴定、Job's plot、ESI-MS 和 DFT 计算进行。结果表明,传感器 1a-1c 显示出对 Cu2+ 和 Fe3+ 离子的选择性识别,并通过 PET 机制在 DMSO/H2O 溶液(HEPES 的 1:1,v/v,pH 7.4)中形成化学计量比为 1:1 的复合物。计算结合常数 (K) 和检测限。我们报告了三种新型荧光大环传感器的合成,这些传感器包含光学活性丹磺酰基。合成化合物与各种金属离子(Li+、Na+、K+、Ag+、Mg2+、Ca2+、Ba2+、Pb2+、Zn2+、Co2+、Cd
