The newly synthesized cyclotriphosphazene cored coumarin chemosensors 5, 6, and 7 were successfully characterized by H NMR, P NMR, and MALDI-TOF mass spectrometry. Additionally, the photophysical and metal sensing properties of the targeted compounds were determined by fluorescence spectroscopy in the presence of various metals (Li , Na , K , Cs , Mg , Ca , Ba , Cr , Mn , Fe , Co , Al , Hg , Cu , Zn , Ag , and Cd ) . The fluorescence titration results showed that compounds 5, 6, and 7 could be employed as fluorescent chemosensors for Fe ions with high sensitivity. The complex stoichiometry between final cyclotriphosphazene chemosensors and Fe ions was also determined by Job's plots.
新合成的以环三磷腈为核心的香豆素化学传感器5、6和7通过氢核磁共振（¹H NMR）、磷核磁共振（³¹P NMR）和基质辅助激光解吸电离飞行时间质谱（MALDI-TOF质谱）成功进行了表征。此外，在存在各种金属（锂离子、钠离子、钾离子、铯离子、镁离子、钙离子、钡离子、铬离子、锰离子、铁离子、钴离子、铝离子、汞离子、铜离子、锌离子、银离子和镉离子）的情况下，通过荧光光谱法测定了目标化合物的光物理和金属传感特性。荧光滴定结果表明，化合物5、6和7可作为对铁离子具有高灵敏度的荧光化学传感器。最终的环三磷腈化学传感器与铁离子之间的络合化学计量关系也通过乔布氏曲线进行了测定。
