Cu-BTC[Cu-3(BTC)(2)(H2O)(3), BTC = 1,3,5-苯三甲酸]是最著名的金属有机骨架材料（MOF）之一，是在大气压和室温下利用超声波合成的。在DMF（N,N-二甲基甲酰胺）存在下，1分钟内即可获得Cu-BTC，这表明连续生产Cu-BTC的可能性。此外，表面积和孔体积表明DMF的浓度对于合成具有高孔隙率的Cu-BTC很重要。形态和相还取决于 DMF 的浓度：在没有 DMF 的情况下，在室温下无法获得 Cu-BTC，而在高浓度 DMF 存在的情况下会产生聚集的 Cu-BTC（具有低表面积）。看来室温合成中苯三甲酸被碱（如DMF）去质子化是不可避免的。
Cu-BTC[Cu-3(BTC)(2)(H2O)(3), BTC = 1,3,5-benzenetricarboxylate], one of the most well-known metal-organic framework materials (MOF), has been synthesized under atmospheric pressure and room temperature by using ultrasound. The Cu-BTC can be obtained in 1 min in the presence of DMF (N,N-dimethylformamide), suggesting the possibility of continuous production of Cu-BTC. Moreover, the surface area and pore volume show that the concentration of DMF is important for the synthesis of Cu-BTC having high porosity. The morphology and phase also depend on the concentration of DMF : Cu-BTC cannot be obtained at room temperature in the absence of DMF and aggregated Cu-BTC (with low surface area) is produced in the presence of high concentration of DMF. It seems that the deprotonation of benzenetricarboxylic acid by base (such as DMF) is inevitable for the room temperature syntheses.
