A simple coumarin hydrazine Schiff base bearing a thioether recognition fragment (compound ) has been rationally designed and easily prepared. exhibited an excellent selectivity for Pd(II) and a low detection limit of 65 nM (S/N = 3). The fluorescence emission intensities of at 495 nm were linear to Pd(II) concentrations in a wide range from 0 to 80 μM. Moreover, has been well used in fluorescence imaging of Pd(II) in living A549 cells. as a simple coordination-based fluorescent probe will inspire the researchers to develop a polymer for selective detection and adsorption of Pd(II).
一种带有硫醚识别片段的简单香豆素肼席夫碱（化合物 ）已被合理设计并易于制备。该化合物对 Pd(II) 表现出优异的选择性，检测限低至 65 nM（信噪比 = 3）。在 495 nm 处该化合物的荧光发射强度与 Pd(II) 浓度在 0 至 80 μM 的宽范围内呈线性关系。此外，该化合物已成功用于活的 A549 细胞中 Pd(II) 的荧光成像。作为一种简单的基于配位的荧光探针，该化合物将激励研究人员开发一种用于选择性检测和吸附 Pd(II) 的聚合物。
