Rhodamine is an ideal platform for fluorescence probes owing to its spiro-lactam framework and excellent photochemical properties. Herein, a novel rhodamine-based palladium fluorescent chemosensor, Rd-Eb, showing a fast response time (3 min), high sensitivity for palladium species over other ions, and a low detection limit (1.91×10(-7) m), was synthesized. It can act as an obvious colorimetric as well as a fluorescent "off/on" sensor for Pd(2+) . In addition, it is also an excellent sensor for in vivo imaging of Pd(2+) in zebra fish and Daphnia magna, illuminating the impact of palladium on organisms at different growth stages with respect to biological toxicology.
由于其螺内酰胺骨架和优异的光化学性质，罗丹明是荧光探针的理想平台。在此，合成了一种新型的基于罗丹明的钯荧光化学传感器Rd-Eb，它具有快速响应时间（3分钟）、对钯离子比对其他离子具有高灵敏度以及低检测限（1.91×10⁻⁷ m）。它可以作为Pd²⁺的明显比色和荧光“关/开”传感器。此外，它也是斑马鱼和大型溞体内Pd²⁺成像的优秀传感器，从生物毒理学角度阐明了钯在不同生长阶段对生物体的影响。
