We report a coumarin-derived fluorescent sensor for Zn(2+) termed CTS. CTS shows excellent binding selectivity for Zn(2+) over competing metal ions due to the transformable ability of CTS, that is the displacement of other metal ions by Zn(2+), which induces transformation of chelation from an amide to an imidic acid tautomeric form.
我们报告了一种基于香豆素的荧光传感器 CTS，用于检测 Zn(2+)。CTS 对 Zn(2+)具有出色的结合选择性，优于竞争金属离子，这归因于 CTS 的可变形能力，即 Zn(2+)取代其他金属离子，从而诱导酰胺到酰亚胺互变异构形式的螯合转变。
