摘　　要：通过简单高效的醛酮缩合反应,合成了碱性配体2,6-二(4-吡啶基亚甲基)环己酮(BPCH),采用3种芳香羧酸配体:对苯二甲酸(H_(2)TP)、间苯二甲酸(H_(2)IP)和均苯三甲酸(H_(3)TMA),以混合配体策略制备了7例金属有机骨架(MOFs)。用单晶X射线衍射、红外光谱、粉末X射线衍射和热重分析对其进行表征并分析其拓扑结构。MOFs1、2、3均呈现为多样的三维结构,MOFs4~7表现为同构的二维结构。荧光测试结果显示该类化合物对Fe^(3+)有较好的荧光猝灭效应,同时对于染料具有一定的吸附能力。Taking advantage of a basic ligand (BPCH=2,6-bis(4-pyridyl methylidene)cyclohexanone) and three acid ligands (H_(2)TP=terephthalic acid,H_(2)IP=isophthalic acid,H_(3)TMA=1,3,5-benzenetricarboxylic acid),seven metal-organic frameworks (MOFs)1-7have been achieved by using this acid-base mixedligand synthetic strategy.These complexes were characterized by single-crystal X-ray diffraction,IR spectra,powder X-ray diffraction,and thermogravimetric analysis.Diverse 3D structural characters of MOFs1-3or 2D structural characters of MOFs4-7have been observed.The fluorescence properties of these complexes have been explored,indicating that they had selectivity towards Fe^(3+)ions.Several complexes had shown certain performance for adsorbing dye molecules.CCDC:2165701,BPCH;2083177,1;2083167,2;2083174,3,2106783,4;2106784,5;2106785,6;2106786,7.
