In this study, a new phenolphthalein derivative, FFIZNA, has been planned and successfully prepared in an uncomplicated way. The probe FFIZNA could selectively monitor Al and Zn among other relevant cations with diverse colors through a turn-on emission response in EtOH:HEPES (9/1;v/v) media owing to the chelation enhanced fluorescence (CHEF), prevention of ESIPT, -C=N- isomerization and PET of the probe FFIZNA. The interactions of Al and Zn with the probe FFIZNA were confirmed by emission spectroscopy, Job's plot and H-NMR titration substantiated 1:2 reaction stoichiometry between FFIZNA and Al and Zn. The time-response study displayed that the emission of FFIZNA with Al and Zn, rapidly boosted and reached the stable value in less than 3.0 and 4.0 min, respectively. Therefore, the FFIZNA has successfully been utilized to the dual recognition of Al and Zn in solutions. Phenolphthalein conjugated schiff base as a dual emissive fluorogenic probe for the detection aluminum (III) and zinc (II) ions.
在这项研究中，我们设计并成功地以一种简单的方式制备了一种新的酚酞衍生物 FFIZNA。探针 FFIZNA 可以通过在 EtOH:HEPES（9/1；v/v）介质中由于螯合增强荧光（CHEF）、ESIPT 的阻止、-C=N-异构化和探针 FFIZNA 的 PET，以开启式发射响应选择性地监测 Al 和 Zn 以及其他相关阳离子，呈现出不同的颜色。通过发射光谱、Job 图和 H-NMR 滴定实验证实了 Al 和 Zn 与探针 FFIZNA 的相互作用，证明了 FFIZNA 与 Al 和 Zn 之间的反应计量比为 1:2。时间响应研究表明，FFIZNA 与 Al 和 Zn 的发射在不到 3.0 和 4.0 分钟内迅速增强并达到稳定值。因此，FFIZNA 已成功用于溶液中 Al 和 Zn 的双重识别。苯并菲共轭席夫碱作为一种双发射荧光探针，用于检测铝（III）和锌（II）离子。
