摘要

通过共轭配体和金属离子之间的主客体相互作用，构建了一种网络结构的超分子凝胶，从而增强了机械性能和优异的导电性。这克服了由于超分子凝胶间隙区存在溶剂而导致导电性不足的问题。通过控制体系的 pH 值或温度，超分子凝胶可发生可逆的溶胶-凝胶转变。此外，还开发了一种通过电导测试确定主客分子特定结合率的方法，并已用于验证冠醚与钾离子的特定结合率。为了解释超分子金属凝胶的高导电性，采用了 DFT 和 SEM 来阐明其导电机制。

A Supramolecular Gel that Exhibits Multi-stimuli Responsiveness and High Conductivity Through Host-Guest Interactions

A network-structured supramolecular gel is constructed through host-guest interactions between conjugated ligands and metal ions, leading to enhanced mechanical properties and excellent electrical conductivity. This overcomes the problem of insufficient conductance due to the presence of solvent in the interstitial region of the supramolecular gel. Supramolecular gels can undergo reversible sol-gel transitions by controlling the pH or temperature of the system. In addition, a method has been developed to determine the specific binding ratio of host-guest molecules by conductivity tests, and has been used to verify the specific binding ratio of crown ether to potassium ions. To explain the high conductivity of supramolecular metallic gels, DFT and SEM have been employed to elucidate their conductivity mechanism.
