摘　　要：以含羟基官能团的三羧酸配体和硝酸锌为原料,N,N-二甲基甲酰胺为溶剂,通过溶剂热法合成新型锌金属有机骨架材料.考察了金属盐、羧酸配体和有机溶剂用量,以及反应温度、反应时间对反应的影响,确定较优的合成反应条件为:金属盐与羧酸配体的摩尔比为1.5∶1,有机溶剂与羧酸配体的摩尔比为300∶1,反应温度为110℃,反应时间为48 h.在此反应条件下,能够制备出结晶度较高的金属有机骨架材料.Using tricarboxylic acid ligand containing hydroxyl functional group and zinc nitrate as raw materials,a new zinc metal organic framework was synthesized by solvothermal method with N,N-dimethylformamide as solvent.The effects of the amount of metal salt,carboxylic acid ligand and organic solvent,reaction temperature and reaction time on the reaction were discussed.The optimal synthetic reaction conditions were determined.The molar ratio of metal salt to carboxylic acid ligand was 1.5∶1.The molar ratio of organic solvent to carboxylic acid ligand was 300∶1.The reaction temperature was 110℃,and the reaction time was 48 h.Under these conditions,metal organic framework materials with high relative crystallinity can be synthesized.
