the gel network, which was exploited as a template to generate highly aligned 1D silica fibers. The gelator D‐3‐PyTA was also exploited to generate metallogels by treatment with various CuII/ZnII salts under suitable conditions. A structure–property correlation on the basis of single‐crystal and powder X‐ray diffraction data was attempted to gain insight into the structures of the gel networks in both
合成了一系列源自L -(+)-酒石酸的双酰胺,作为潜在的低分子量胶凝剂。在合成的14种双酰胺中,有13种表现出有机,水和灵巧的凝胶化行为。通过包括圆二色性,差示扫描量热法,光学和电子显微镜以及流变学在内的方法对凝胶进行表征。其中一种衍生自二-3-吡啶基酒石酰胺(D-3-PyTA)的凝胶显示出有趣的凝胶网络纳米管形态,被用作模板以生成高度对齐的一维二氧化硅纤维。胶凝剂D‐3‐PyTA也被用来通过用各种Cu II / Zn II处理生成金属盐在适当条件下的盐。试图根据单晶和粉末X射线衍射数据进行结构-性质相关性分析,以了解有机和金属凝胶中凝胶网络的结构。这项研究导致确定了基于Cu II配位聚合物的Metallogel的凝胶网络结构,该凝胶结构显示了由氯离子桥接的双螺旋制成的2D薄板结构,类似于5 c净SnS拓扑结构。
