A new fluorescence rhodamine derivative bearing an 8-aminoquinoline moiety has been designed and synthesized for selective sensing of Pd2+ in the presence of other competing metal ions in aqueous media. Pd2+ induced spirolactam ring opening of rhodamine is confirmed for the first time by the X-ray crystal structure of the bound Pd2+-complex.
设计并合成了一种带有 8-氨基喹啉部分的新型荧光罗丹明衍生物,用于在水介质中存在其他竞争性金属离子的情况下选择性传感 Pd2+。结合的 Pd2+ 配合物的 X 射线晶体结构首次证实了 Pd2+ 诱导罗丹明的螺内酰胺开环。
