width of a single molecule of the hydrogelator. These results illustrate that metal complexes, besides being able to impart rich optical, electronic, redox, or magnetic properties to supramolecular hydrogels, also offer a unique geometrical control to prearrange the self-assembly motif prior to self-assembling. The use of metal complexes to modulate the dimensionality of intermolecular interactions may
三肽衍生物是一种多功能的自组装基序,与钌(II)三(联吡啶)络合物的整合提供了第一个超分子金属水凝胶剂,它不仅在水中自组装形成水凝胶,而且还具有凝胶-金属中心氧化时的溶胶转变。令人惊讶的是,在水凝胶剂中引入金属络合物导致纳米纤维,由水凝胶剂在水中的自组装形成,具有水凝胶剂的单个分子的宽度。这些结果表明,金属配合物除了能够赋予超分子水凝胶丰富的光学、电子、氧化还原或磁性特性外,还提供了一种独特的几何控制,可以在自组装之前预先安排自组装基序。
