Supramolecules mediated porous metal nanostructures are meaningful materials because of their specific properties and wide range of applications. Here, we describe a general and simple strategy for building Au-networks based on the guest-induced 3D assembly of Au nanoparticles (Au-NPs) resulted in host-guest interaction resolved sulfonatocalix[4]arene (pSC₄)-modified Au-NPs aggregate. The diverse guest molecules induced different porous network structures resulting in their different oxidize ability toward glucose. Among three different kinds of guest, hexamethylenediamine-pSC₄-Au-NPs have high sensitivity, wide linear range and good stability. By surface characterization and calculating the electrochemical properties of the Au-NPs networks modified glassy carbon electrodes, the giving Au-NPs network reveals good porosity, high surface areas and increased conductance and electron transfer for the electrocatalysis. The synthesized nano-structures afford fast transport of glucose and ensure contact with a larger reaction surface due to high surface area. The fabricated sensor provides a platform for developing a more stable and efficient glucose sensor based on supramolecules mediated Au-NPs networks.

客体介导的超分子修饰的金纳米颗粒网络用于模拟酶的应用

超分子介导的多孔金属纳米结构是有意义的材料，因为它们的特殊性能和广泛的应用范围。在这里，我们描述了一种基于Au纳米粒子（Au-NPs）的客体诱导3D组装而建立Au网络的通用且简单的策略，这种3D组装导致了宿主与客体之间的相互作用，从而解决了磺基杯[4]芳烃（pSC ₄）修饰的Au- NP聚合。不同的客体分子诱导不同的多孔网络结构，从而导致其对葡萄糖的不同氧化能力。在三种不同的客人中，六亚甲基二胺-pSC ₄-Au-NP具有高灵敏度，宽线性范围和良好的稳定性。通过表面表征和计算Au-NPs网络修饰的玻碳电极的电化学性能，得到的Au-NPs网络显示出良好的孔隙率，高表面积以及用于电催化的增加的电导和电子转移。合成的纳米结构提供了葡萄糖的快速运输，并由于高表面积而确保与更大的反应表面接触。制成的传感器提供了一个平台，用于开发基于超分子介导的Au-NPs网络的更稳定和有效的葡萄糖传感器。
