文摘

A series of amine-functionalized mixed-linker metal鈥搊rganic frameworks (MOFs) of idealized structural formula Zr₆O₄(OH)₄(BDC)_6鈥?X(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鈥搗isible light (UV-vis) spectroscopy in the quantification of ABDC in mixed-linker MOFs.
