Wu, Zi-ying; Xu, Zhong-yong; Yan, Jin-wu; Li, Yafang; Kou, Qiuye; Zhang, Lei published the artcile< Development of rhodamine-based fluorescent probes for sensitive detection of Fe3+ in water: spectroscopic and computational investigations>, Category: indole-building-block, the main research area is rhodamine iron water fluorescent probe.
Four novel rhodamine-based fluorescent probes (RE1-RE4) were designed and synthesized for sensitive detection of Fe3+ in H2O. RE1-RE4 exhibited low detection limits in the range of 18.6 nM to 29.4 nM. The binding modes of the probes (RE1-RE4) with Fe3+ are 1:1 stoichiometry of the complexes by Job’s plot and also their complexing ability was determined using the binding constants (RE2 > RE4 > RE3 > RE1). RE2 was selected to study the proposed binding mechanism with Fe3+ by ESI-MS, 1H NMR and DFT calculations Also, RE2 was further used to detect Fe3+ in living cells and real H2O samples, indicating its promising prospect in biol. and environmental fields.
New Journal of Chemistry published new progress about Fluorescence spectroscopy. 950846-89-6 belongs to class indole-building-block, and the molecular formula is C30H36N4O2, Category: indole-building-block.
