A series of amine-functionalized mixed-linker metal-organic frameworks (MOFs) of idealized structural formula Zr6O4(OH)4(BDC)(6-6X)(ABDC)6X (where BDC = benzene-1,4-dicarboxylic acid, ABDC = 2-aminobenzene-1,4-dicarboxylic acid) has been prepared by solvothermal synthesis. The materials have been characterized by thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD), and Fourier transform infrared (FTIR) spectroscopy with the aim of elucidating the effect that varying the degrees of amine functionalization has on the stability (thermal and chemical) and porosity of the framework. This work includes the first application of ultraviolet-visible light (UV-vis) spectroscopy in the quantification of ABDC in mixed-linker MOFs.
通过溶剂热合成制备了一系列具有理想结构通式Zr6O4(OH)4(BDC)(6 - 6X)(ABDC)6X（其中BDC = 对苯二甲酸，ABDC = 2-氨基对苯二甲酸）的胺官能化混合连接体金属有机框架材料（MOF）。通过热重分析（TGA）、粉末X射线衍射（PXRD）和傅里叶变换红外（FTIR）光谱对这些材料进行了表征，目的是阐明改变胺官能化程度对框架稳定性（热稳定性和化学稳定性）及孔隙率的影响。这项工作首次将紫外-可见光谱（UV-vis）用于混合连接体MOF中ABDC的定量分析。
