摘要: 以1, 3, 5-均苯三甲酸(H3BTC)和4, 4′-联吡啶(4, 4′-bpy)为有机配体,Cu(Ac)2·H2O作为铜源,通过水热法成功合成了一种二维(2D)铜基-有机框架(MOF),Cu2(HBTC)2(4, 4′-bpy)2·5H2O(配合物1)。采用X射线衍射、元素分析和傅里叶变换红外光谱(FT-IR)等手段确定了配合物1的结构。结果表明,配合物1属于单斜晶系C2/c空间群,其不对称单元包含一个Cu2+、一个去质子化HBTC2-、一个4, 4′-bpy和三个结晶水分子。在有机染料吸附性能探究中配合物1表现出对亚甲基蓝的优异选择性吸附性能,去除率高达93.4%。此外,配合物1在65 ℃、98%相对湿度下表现出7.32×10-4 S·cm-1的质子电导率。本研究为MOFs在染料吸附和质子导电材料领域的应用提供了新的思路。

Abstract: A two-dimensional (2D) copper-based metal-organic framework (MOF),[Cu2(HBTC)2(4, 4′-bpy)2·5H2O] (complex 1), was successfully synthesized via a hydrothermal method, using 1, 3, 5-benzenetricarboxylic acid (H3BTC) and 4, 4′-bipyridine (4, 4′-bpy) as organic ligands, and Cu(Ac)2·H2O as the copper source. The structure of complex 1 was determined by X-ray diffraction, elemental analysis, and Fourier-transform infrared spectroscopy (FT-IR). The results show that complex 1 belongs to the monoclinic crystal system, space group C2/c, with the asymmetric unit containing one Cu2+, one deprotonated HBTC2-, one 4, 4′-bpy, and three crystalline water molecules. In the exploration of organic dye adsorption capabilities, complex 1 demonstrates an excellent selective adsorption performance for methylene blue, achieving a removal rate of up to 93.4%. In addition, complex 1 shows a proton conductivity of 7.32×10-4 S·cm-1 at 65 ℃ and 98% RH. This study provides new insights into the application of MOFs in dye adsorption and proton conductive materials.
