Rhodamine-based chemosensors are widely used for the detection of various metal ions and applied in many fields of science including biological and environmental sciences. Rhodamine derivatives remain colorless and almost nonfluorescent when their spirolactam ring remains in closed form. They become pink or purple and strongly fluorescent upon opening of the ring. A particular metal ion can induce the ring opening process under a set of conditions and the process of selective sensing is dependent on many factors. Differentiation of metal sensing using rhodamine dyes is achieved in various ways which include selection of solvent, pH, mode of interaction with the cations, and so on. We have incorporated more than 140 research articles here to discuss the structure-property correlation of rhodamine based chemosensors. We have tried to correlate metal ion selectivity and structures of the chemosensors for the first time for rhodamine derivatives.
基于若丹明的化学传感器广泛用于检测各种金属离子，并应用于包括生物和环境科学在内的许多科学领域。当螺环酰胺环处于闭合形式时，若丹明衍生物仍然是无色且几乎无荧光的。当环打开时，它们会变成粉红色或紫色，并具有强烈的荧光。在一组条件下，特定的金属离子可以诱导环的打开过程，并且选择性传感的过程取决于许多因素。使用若丹明染料进行金属传感的区分是通过多种方式实现的，包括溶剂的选择、pH 值、与阳离子相互作用的模式等。我们在这里收录了超过 140 篇研究文章，讨论了基于若丹明的化学传感器的结构-性质相关性。我们首次尝试为若丹明衍生物关联金属离子选择性和化学传感器的结构。
