Hierarchical self-assembly has been recently employed in the construction of anion-coordination-driven gel materials. However, the post-assembly modification strategy, which may be a highly efficient strategy to realize the functionalization of discrete 'aniono' supramolecular architectures, has not been employed yet. Herein we report the first example of anion-coordination-driven gel material cross-linked by well-defined 'aniono' triple helicate through post-assembly polymerization. The obtained gel shows self-healing property and excellent compatibility with various surfaces, including glass, rubber, leaf, PP, and metal. The viscoelastic gel constructed through the post-assembly modification strategy enriches the method to construct the anion-coordination-driven smart materials.
分层自组装最近已被用于构建阴离子配位驱动的凝胶材料。然而,后组装修饰策略,这可能是实现离散“阴离子”超分子结构功能化的一种高效策略,尚未被采用。在此,我们报道了首例通过后组装聚合,由明确的“阴离子”三螺旋体交联的阴离子配位驱动的凝胶材料。所获得的凝胶具有自愈性能,并且与包括玻璃、橡胶、树叶、聚丙烯和金属在内的各种表面具有优异的相容性。通过后组装修饰策略构建的粘弹性凝胶丰富了构建阴离子配位驱动的智能材料的方法。
