摘要
选取4,4′-联苯二甲酸(4,4′-H2BPDC)和2,6-萘二甲酸(2,6-H2NDC)分别与二氯二茂锆(Cp2ZrCl2)反应制备了2例结构新颖的锆基纳米分子胶囊[Cp3Zr3(μ3-O)(μ2-OH)3]2(BPDC)3Cl2·H2O(Zr-MC-1)和[Cp3Zr3(μ3-O)(μ2-OH)3]2(NDC)3Cl2·3H2O(Zr-MC-2)。这2个分子胶囊均由3个线性羧基配体桥联2个三核茂锆建筑单元构成。利用单晶X射线衍射、粉末X射线衍射、元素分析、红外光谱、热重分析和氮气吸附-脱附等手段对化合物进行了表征。此外,荧光光谱分析表明Zr-MC-1和Zr-MC-2分别为深蓝光和蓝光发射材料,其最大发射波长分别为404和456nm。
Two nanosized zirconium-based molecular capsules (Zr-MCs), namely [Cp3Zr3(μ3-O)(μ2-OH)3]2(BPDC)3Cl2 ·H2O (Zr-MC-1) and [Cp3Zr3(μ3-O)(μ2-OH)3]2(NDC)3Cl2·3H2O (Zr-MC-2), have been synthesized by reacting zirconocenedichloride (Cp2ZrCl2) with 4,4′-biphenyldicarboxylic acid (4,4′-H2BPDC) and 2,6-naphthalenedicar-boxylic acid (2,6-H2NDC), respectively, which are constructed by two trinuclear zirconocene building blocks and three linear carboxylate ligands. They were characterized by single-crystal X-ray diffraction, powder X-ray diffraction, elemental analysis, IR spectroscopy, thermogravimetric analysis and N2 adsorption-desorption tests. In addition, the fluorescence spectra indicate that Zr-MC-1 and Zr-MC-2 are deep-blue and blue emitting materials with emission peaks at 404 and 456 nm, respectively. CCDC: 939840, Zr-MC-1;939841, Zr-MC-2.
