Abstract In this present study, A newly designed and synthesized probe specifically (E)-1-(((2-(phenylthio)phenyl)imino)methyl)naphthalen-2-ol (NAPTA) as efficient chemosensor was portrayed through the utilization of various spectroscopic techniques like 1H, 13C NMR and ESI-MS. The probe exhibits fantastically specific and sensitive towards Al3+ ions than the other contending cationic metal ions. This designed probe indicates chromogenic and turn-on fluorescence behavior which may be noticeable through naked-eye and UV light individually. The 1:1 binding interaction of NAPTA with Al3+ ions was revealed from the Job’s plot investigation. The limit of detection was determined as 13x 10-7 M which is very lower level than the permitted level. The DFT figuring and calculations have furthermore upheld to the proposed mechanism as CHEF and ICT from the acquired spectroscopic outcomes.

用于选择性和灵敏识别 Al3+ 离子的显色和荧光开启传感器——一种新方法 Schiff 碱衍生物作为探针

摘要 在本研究中，一种新设计和合成的探针特别是（E）-1-（（（2-（苯硫基）苯基）亚氨基）甲基）萘-2-醇（NAPTA）作为有效的化学传感器，通过利用各种光谱技术，如 1H、13C NMR 和 ESI-MS。与其他竞争性阳离子金属离子相比，该探针对 Al3+ 离子表现出惊人的特异性和敏感性。这种设计的探针指示显色和开启荧光行为，这些行为可能分别通过肉眼和紫外光观察到。Job's plot 调查揭示了 NAPTA 与 Al3+ 离子的 1:1 结合相互作用。检测限被确定为 13x 10-7 M，这是非常低于允许水平的水平。
