Crystal structures of a rhodamine derivative in its closed and open spirolactam ring forms were developed, which allows selective and sensitive detection of Cu ions at a micromolar range in neutral medium. The chemosensing properties of the probe through a pentacoordinate Cu ions were proven by spectroscopic and theoretical analysis. The spirolactam ring opening as the Cu selective sensor was applied to spinach () to estimate the accumulation of copper as copper(II) in the plant.
开发了一种罗丹明衍生物处于闭环和开环螺内酰胺环形式的晶体结构，这使得在中性介质中能够在微摩尔范围内选择性且灵敏地检测铜离子。通过光谱和理论分析证明了该探针通过五配位铜离子的化学传感特性。作为铜选择性传感器的螺内酰胺环开环被应用于菠菜中，以估计植物中作为铜（II）的铜的积累量。
