The gelation ability of 5-(1-1,2,3-triazol-5-yl)isophthalic acid () in the presence of different metal acetates has been studied in different solvents and ligand/metal ratios. This manuscript is focused on the metallogel obtained from the combination of and copper(II) acetate, which has been used as a model system in terms of characterization and gelation studies. Sonication treatment of the initial mixture of compounds and the nature of the counter anion were found to be critical factors for the supramolecular assembly of the metal/ complexes and, hence, for the formation of stable and homogeneous metallogels. The gel materials have been characterized with a variety of techniques including infrared, rheology, UV-vis spectroscopy, powder X-ray diffraction, and scanning electron microscopy.
在不同溶剂和配体/金属比例条件下，研究了5-(1-1,2,3-三唑-5-基)间苯二甲酸（）在不同金属醋酸盐存在时的凝胶化能力。本论文聚焦于由和醋酸铜(II)组合得到的金属凝胶，在表征和凝胶化研究方面将其用作模型体系。发现对化合物初始混合物进行超声处理以及抗衡阴离子的性质是金属/配合物超分子组装的关键因素，因此也是形成稳定且均匀金属凝胶的关键因素。已采用多种技术对凝胶材料进行了表征，包括红外光谱、流变学、紫外可见光谱、粉末X射线衍射和扫描电子显微镜。
