using fluorescence spectroscopy. The fluorescence titration results showed that compounds 6 and 7 can be used as fluorescent chemosensors with high selectivity and sensitivity for Cu2+ and Fe3+ ions. Also, the complex stoichiometry of the final cyclotriphosphazene chemosensors and Cu2+/Fe3+ ions was determined by a Job's plot.
摘要在本研究中,已经成功合成了新的基于氨基py的环三磷腈化学传感器6和7。所有合成的环三磷腈化合物的身份已通过1H,31P NMR和MALDI-TOF质谱证实。在多种金属(Li +,Na +,K +,Cs +,Mg2 +,Ca2 +,Ba2 +,Mn2 +,Fe3 +,Cr3 +,Co2 +,Ni2 +,Cu2 +,Cd2 +,Al3 +,Hg + ,Zn2 +)。荧光滴定结果表明,化合物6和7可以用作荧光化学传感器,对Cu2 +和Fe3 +离子具有高选择性和敏感性。同样,最终的环三磷腈化学传感器和Cu2 + / Fe3 +离子的复杂化学计量是通过Job's图确定的。
