A 3-D Zn(II) based metal−organic framework (MOF) of [Zn₄(oba)₃(DMF)₂] was synthesized using the nonlinear dicarboxylate ligand, 4,4′-oxybis(benzoic acid) (H₂oba) via sonochemical and solvothermal routes. IR spectroscopy, single-crystal X-ray crystallography, scanning electron microscopy, and X-ray powder diffraction were used to characterize these MOF samples. The effect of different times of irradiation and various concentrations of primary reagents were experimented for obtaining monotonous morphology. The results show that uniform nanoplates can be achieved by increasing the time of irradiation and decreasing the concentration. N₂ adsorption was applied to examine the effect of synthesis method on porosity of the framework. Also Congo red and Sudan red dyes were employed to explore the efficiency of this MOF in removal of the dye pollutants.

使用非线性二羧酸酯配体4,4'-氧双（苯甲酸）（H ₂）合成了[Zn ₄（oba）₃（DMF）₂ ]的3-D Zn（II）基金属有机骨架（MOF）oba）通过声化学和溶剂热途径。红外光谱，单晶X射线晶体学，扫描电子显微镜和X射线粉末衍射被用来表征这些MOF样品。实验了不同时间的照射和各种浓度的主要试剂的影响，以获得单调的形态。结果表明，可以通过增加辐照时间和降低浓度来获得均匀的纳米板。N ₂采用吸附法研究了合成方法对骨架孔隙率的影响。刚果红和苏丹红也用于研究MOF去除染料污染物的效率。
