| 采用以水为唯一溶剂的绿色路线合成了金属有机骨架(MOFs)材料．通过将羧酸类配体转化为水
溶性铵盐配体,在水溶液中探索了金属有机骨架材料的绿色合成．以醋酸铜(Cu(OAc)2)
和对苯二甲酸(H2BDC)甲胺盐在水溶液中反应,获得了化合物CuBDC\|H2O．同时作为参照,以Cu(OAc)2和H2BDC在N, N-二甲基甲酰胺(DMF)和水的混合溶液中,获得了化合物CuBDC-DMF．通过粉末XRD、IR、SEM、TGA以及N2吸附测试等手段对两种产物进行了表征,结果显示经140 ℃真空热处理10 h后,化合物CuBDC-DMF具有和在水溶液中直接获得的产物CuBDC-H2O相同的晶体结构及相似的性质,而且以水作为反应介质的新的合成路线具有便捷、快速、低成本及节约能源等特点． |

| A green process for the synthesis of metal\|organic frameworks (MOFs)
particles that uses water as the only solvent is presented. The strategy is to convert carboxylic acids ligands into carboxylate ammonium salts ligands which have high solubility in water, thus allowing the synthesis to be performed in water.CuBDC-H2O (BDC=1,4-benzenedicarboxylate) is synthesized by mixing aqueous solutions of Cu(OAc)2 and the methylammonium salt of H2BDC. As a reference, CuBDC-DMF is obtained by mixing water solution of Cu(OAc)2 with DMF solution of H2BDC. The two compounds are characterized by powder XRD, IR, SEM, TGA and N2 and adsorption measurements. The experimental results reveal that after evacuation at 140 ℃ for 10 h, CuBDC-DMF has the same crystal structure and properties with CuBDC-H2O, and the new synthetic route performed in water solution has the advantages of being straight forward, rapid, cheap and energy-saving. |
