摘要:

分子光谱法具有灵敏度高、操作简单等优点,发展简便、快捷、对镍离子(Ni2+)具有高度选择性的探针具有非常重要的意义。 本文以金属离子诱导罗丹明酰胺衍生物反应开环的策略,设计并合成了对Ni2+检测具有单一选择性识别的紫外吸收探针。 同时,该探针可对水溶液中的Ni2+实现“裸眼”识别。 此外,该探针对Ni2+具有较高的灵敏度,其对水溶液中Ni2+的检测限为0.5 μmol/L,表明该探针可用于Ni2+的检测分析。

关键词: 分子探针, 罗丹明B, Ni2+, “裸眼”识别

Abstract:

Molecular spectroscopy has the advantages of high sensitivity and simple operation. Therefore, it is significant to develop a probe with high selectivity for nickel ions(Ni2+). In this paper, a novel molecular probe was designed and synthesized from rhodamine B, hydrazine hydrate and 2-acetylpyrazine for the detection of Ni2+ with excellent selectivity in aqueous media. Simultaneously, the probe rhodamine B amide derivative(RWZ) can achieve “naked eye” recognition of Ni2+ in aqueous solution. Furthermore, the probe shows high sensitivity to Ni2+ with low limit of detection(0.5 μmol/L), indicating that the probe can be used for detection of Ni2+ in aqueous solution.

Key words: molecular probe, rhodamine B, nickel ion, “naked-eye&rdquo, identification
