A new C3-symmetric Schiff-base fluorescent probe (L) based on 8-hydroxy-2-methylquinoline has been developed. As expected, the probe L can display high fluorescent selectivity for Cd(2+) over Zn(2+) and most other common ions in neutral ethanol aqueous medium. Moreover, the mechanism of the L-Cd(2+) complex has been confirmed by X-ray crystallography and density functional theory calculation results. More importantly, L could be used to image Cd(2+) within living cells.
一种基于8-羟基-2-甲基喹啉的新型C3对称席夫碱荧光探针（L）已被开发出来。正如预期的那样，在中性乙醇水溶液介质中，探针L对Cd(2+) 相对于Zn(2+) 和大多数其他常见离子可表现出高荧光选择性。此外，L-Cd(2+) 配合物的机理已通过X射线晶体学和密度泛函理论计算结果得到证实。更重要的是，L可用于对活细胞内的Cd(2+) 进行成像。
