| 摘要: 以3，5-双（4-羧基-苯氧基）苯甲酸（H3BCPBA）、1，3-双（咪唑基）丙烷（bip）与硝酸镉为反应物，在水热、溶剂热条件下以不同的反应温度和不同的降温速率，分别合成出了2种金属-有机骨架（MOF）化合物：{[Cd1.5（BCPBA）（bip）]·H2O·DMF}n（1）和[Cd1.5（BCPBA）（bip）0.5（H2O）]n （2）。通过X射线单晶衍射（XRD）确定其结构，并用红外光谱（IR）、元素分析、热重（TG）和粉末X射线衍射仪（PXRD）等对其进行表征，并测试了2种化合物的荧光属性。结构表明化合物1中Cd1原子先与3个BCPBA3-配体配位，形成一个一维链结构，2个相邻的一维链通过Cd2原子由羧基氧桥接在一起。然后由含氮配体将一维的双链连结成一个二维的层结构。化合物2是一个由新颖的篮子型六连结的三核Cd（Ⅱ）二级结构单元（SBUs）构筑的二维层结构。 |

| Abstract: Two metal-organic frameworks(MOFs), namely, {[Cd1.5(BCPBA)(bip)]·H2O·DMF}n(1) and [Cd1.5(BCPBA)(bip)0.5(H2O)]n(2) (H3BCPBA=3,5-bis(4-carboxy-phenoxy)benzoic acid, bip=1,3-bis(imidazolyl)propane), have been synthesized under hydrothermal/solvothermal conditions with different reaction temperatures and decreasing temperature rates. Their structures have been determined by single-crystal X-ray diffraction analyses and further characterized by infrared spectra(IR), elemental analyses, and thermogravimetric analyses(TGA). In compound 1, the Cd1 cation is coordinated by three BCPBA3- ligands to form a 1D chain, then two adjacent 1D chain are bridged together by carboxylic oxygen and Cd2 atom. Then the bip ligands join all infinite 1D doublechains into a 2D sheets. In compound 2, trinuclear Cd(Ⅱ) secondardedy building units (SBUs) can be regarded as 6-connected nodes with the BCPBA3-ligands acting as linkers to form a 2D layered network. Photoluminescence properties of 1 and 2 in solid state at room temperature were studied. |
