Metal‐ligand coordination and host–guest recognition are introduced into the hybrid system in order to prepare supramolecular gels, which can be responsive to multiple external stimuli such as metal ions, competitive guest/host molecules, and oxidants. To this end, the triangular terpyridine‐based metallocycles functionalized with 1‐adamantyl and ferrocenyl groups are constructed through self‐assembly, and further used as supramolecular cross‐linkers for gelation of β‐CD‐containing copolymers. Their gelation and stimuli‐response tests are discussed, and an application of the metallotriangles for serving as supramolecular glue is demonstrated through a series of adhesion experiments. This approach enables facile access to construction of multifunctional metallosupramolecules as well as functional hybrid materials.

基于金属配体配位和主客体识别的分层自组装构建的刺激响应超分子凝胶

为了制备超分子凝胶，金属-配体配位和主客体识别被引入到杂化系统中，该分子可以响应多种外部刺激，例如金属离子，竞争性客体/宿主分子和氧化剂。为此，通过自组装构建了由1-金刚烷基和二茂铁基官能化的基于三联吡啶的三角形金属环，并进一步用作超分子交联剂，用于含β-CD共聚物的凝胶化。讨论了它们的胶凝和刺激反应测试，并通过一系列粘合实验证明了金属三角形作为超分子胶的应用。这种方法使得能够容易地获得多功能金属超分子以及功能性杂化材料的构造。
