A colorimetric and fluorescent probe has been designed and synthesized, which bearing the double azine moiety and showing a detection limit of 2.725 × 10 M towards Zn. Based on the basic recognition mechanism of ESIPT and CHEF effect, the has high selectivity and sensitivity to only Zn (not Fe, Hg, Ag, Ca, Co, Ni, Cd, Pb, Cr, and Mg) within the physiological pH range (pH = 7.0-8.4) and showed a fluorescence switch. Moreover, this detection progress occured in the DMSO/HO ∼ HEPES buffer (80/20, v/v; pH 7.23) solution which can conveniently used on test strip.
设计并合成了一种比色和荧光探针，其带有双嗪部分，对锌的检测限为2.725×10⁻⁶ M。基于激发态分子内质子转移（ESIPT）和化学增强荧光（CHEF）效应的基本识别机制，该探针对生理pH范围（pH = 7.0 - 8.4）内的锌具有高选择性和灵敏度（对铁、汞、银、钙、钴、镍、镉、铅、铬和镁无响应），并呈现荧光开关现象。此外，该检测过程在二甲基亚砜/水 ∼ 4-(2-羟乙基)-1-哌嗪乙磺酸缓冲液（80/20，v/v；pH 7.23）溶液中进行，可方便地用于试纸条检测。
