A new strategy to form ordered hierarchical supramolecular gels that incorporate graphene oxide (GO) sheets and cationic rigid macrocyles under mild conditions via self-assembly is demonstrated. These ordered gels are stabilized by a series of non-covalent - donor-acceptor, π-π stacking, cation-π - interactions. These theoretical studies indicate that cationic macrocycles are positioned in between GO layers with a substantial binding energy.
展示了一种新策略，即在温和条件下通过自组装将氧化石墨烯（GO）片和阳离子刚性大环纳入有序的超分子凝胶中。这些有序凝胶通过一系列非共价 - 供体-受体、π-π 堆积、阳离子-π 相互作用稳定。这些理论研究表明，阳离子大环位于 GO 层之间，具有相当大的结合能。
