| 摘要: 选用刚性3，3'，5，5'-四咪唑基联苯(L)作为主配体，分别辅以4，4'-联苯二羧酸(4，4'-H2BPDC)和4，4'-氧二苯甲酸(H2OBA)为第二配体，在水热条件下，成功制备了2种基于Zn (Ⅱ)的金属有机骨架，即[Zn2(L)(BPDC)2]·H2O (1)和[Zn2(L)(OBA)2]·6H2O (2)。单晶X射线衍射表征结构显示：1和2均为(4，4)-连接的二节点的双重贯穿的新型3D孔道结构，其中2具有一定的孔隙率。活化的2(2')的吸附性质表明其对H2O和EtOH具有选择性吸附。 | |

| Abstract: Solvothermal reactions of a tetradentate imidazole-containing ligand, 3,3',5,5'-tetraimidazolyl biphenyl (L), combined with Zn(Ⅱ) salt in the presence of varied auxiliary dicarboxylic acids yield two new metal-organic frameworks (MOFs) with (4, 4) topologies, namely [Zn2(L) (BPDC)2]·H2O (1) and [Zn2(L) (OBA)2] ·6H2O (2), where H2BPDC=4,4'-biphenyldicarboxylic acid, H2OBA=4,4'-oxydibenzoic acid. Single crystal X-ray diffraction analysis has shown that complex 1 consists of 1D chains interconnected by Zn—N bonds, forming a layer structure, which can be further linked by BPDC2- ligands, resulting in the formation of a 3D framework, while complex 2 consists of 2D layers with different 46-membered macrocycles, which are further connected by carboxylates to bring about 3D frameworks. Furthermore, activated complex 2(2') possesses remarkable selective adsorption characteristics for H2O and EtOH. The photoluminescence properties of these MOFs were also thoroughly examined. | |
