The synthesized compounds (1-5 and L) were characterized by FT-IR; H-1, C-13, and P-31 NMR; and MALDI MS spectrometry. The optical sensor features for the Fe3+ complex of L were investigated by UV-vis and fluorescence spectroscopy. The stoichiometry of L-Fe3+ complex was found to be 1:3 (ligand/metal ion), and the detection limit of L was determined as 4.8 mu M (0.27 mg L-1) for Fe3+ ions. The reusability of the sensor was tested by the addition of ethylenediamine to L-Fe3+ complex solutions followed by the addition of Fe3+ solution.eninfo:eu-repo/semantics/closedAccessOff-OnAqueous-SolutionCyclotriphosphazene CoreLiving CellsChemosensorSensitivityHg2+CyclophosphazenesReceptorBehaviorArticle5342144215110.1021/ic402783xQ1WOS:0003321441000362-s2.0-8489429283524498930Q1
