Nanoparticle‐hydrogel hybrid composites have a great potential for a broad range of applications, such as antibacterial materials, stimuli‐responsive materials and catalysis. A novel supramolecular hydrogel system was developed using an amino acid based amphiphile containing a terminal pyrrole moiety as a gelator. The pyrrole moiety could serve as both reducing agent and monomer, and a variety of metal precursors penetrating into the hydrogel could be reduced in situ into metal nanoparticles while the pyrrole moieties preorganized in hydrogel were oxidized into polyprroles, affording metal‐nanoparticle‐decorated covalent conductive networks. This strategy allows the facile fabrication of diverse mono‐ or multimetallic nanoparticle‐polymer networks from one hydrogel by a simple reaction‐diffusion approach. More importantly, besides homogeneous composites, unique multisegment heterogeneous systems with spatiotemporal control were also easily accessible. Furthermore, based on the same multifunctional molecule, the fabrication of hierarchically pore‐structured metal‐nanoparticles‐polymers as well as metal‐nanoparticles‐carbon structures was also realized.

还原性超分子水凝胶：方便制造时空控制的各种金属-纳米粒子装饰的导电网络的平台。

纳米颗粒-水凝胶杂化复合材料具有广泛的应用潜力，例如抗菌材料，刺激响应材料和催化作用。使用含有末端吡咯部分的基于氨基酸的两亲物作为胶凝剂，开发了新型的超分子水凝胶系统。吡咯部分既可以充当还原剂，也可以充当单体，并且渗透到水凝胶中的各种金属前体可以原位还原成金属纳米颗粒，而在水凝胶中预先组织的吡咯部分被氧化成多吡咯，提供了金属-纳米颗粒修饰的共价导电性网络。这种策略允许通过一种简单的反应扩散方法，从一种水凝胶轻松制造各种单金属或多金属纳米粒子-聚合物网络。更重要的是，除了均质复合材料之外，还可以轻松访问具有时空控制的独特多段异质系统。此外，基于相同的多功能分子，还实现了层级孔结构的金属-纳米粒子-聚合物以及金属-纳米粒子-碳结构的制造。
