通过金属有机小分子水凝胶选择性形成实现磷酸根的可视识别

Visual Discrimination of Phosphate Anion via Selective Metallo-Hydrogel Formation

利用磷酸根和钳型三联吡啶锌络合物的金属中心锌离子具有选择性配位的能力,通过金属有机水凝胶的选择性形成实现了对磷酸根的可视识别.在此基础上,利用一系列实验对这类金属有机水凝胶的热稳定性、流变性质、外观样貌进行了详细表征和分析之后提出了对磷酸根选择性识别的可能机理.

Due to high selective coordination ability of phosphate anion to the Zn center of pincer type terpyridine zinc nitrate complexes, intriguing visual recognition of phosphate anion via selective metallo-hydrogel formation has been successfully realized. Based on this interesting result, a series of control experiments were conducted including the study on thermodynamic stability, rheological property and microscopic morphology of the metallo-hydrogel, a plausible mechanism of the discrimination was proposed.
