摘要
A fluorescence enhancement probe WN for detection of Zn2+ with receptor based on di-2-picolylamine (DPA) was synthesized and structurally characterized. Its recognition properties with Zn2+ had been investigated in CH3CH2OH/Tris-HCl buffer solution (1:9, V/V, pH=7.4). The results showed that WN exhibited good sensitivity and selectivity to Zn2+, and the stoichiometry of WN-Zn2+ complex was estimated to be 1:1, the detection limit of Zn2+ was estimated to be 1.14x10(-8) mol.L-1. WN was used for fast visual detection of Zn2+ and its intracelluar Zn2+ imaging in living HeLa cells, indicated that it could be applied in biological detection. CCDC: 960510.
