Construction and Hierarchical Self‐Assembly of a Supramolecular Metal–Carbene Complex with Multifunctional Units

Abstract

AbstractHierarchical combinations involving metal–ligand interactions and host−guest interactions can consolidate building blocks with unique functions into material properties. This study reports the construction and hierarchical self‐assembly of multifunctional trinuclear AuI tricarbene complex containing three crown ether units and three ferrocene units. Host−guest interactions between the multifunctional trinuclear AuI tricarbene complex and organic ammonium salts were investigated, revealing that crown ether‐based host−guest interactions can effectively regulate the electrochemical properties of the complex. Utilizing bisammonium salt as the cross‐linker and multifunctional trinuclear AuI tricarbene complex as the core, a stimuli‐responsive and self‐healing supramolecular gel with different functional units was obtained.
