“…The synthesis of Au I ‐thiolate is through the reaction of Au III ions and thiol ligands in aqueous phase at boiling temperature . Au III ions were first reduced by thiol ligands to Au I and then coordinated with the residual thiol ligands to form linear coordination polymer chains instantly [equation (1)].…”

“…To construct such ah ighly dynamic reaction-coupled self-assembly system,i tn eeds at least two following conditions:f irst, the system should have enough complexity to show multiple stable/metastable structures so that it can adjust its structures amongt hesep ossible ones upon the environmental change; secondly, it should contain components to recognize the change of environments andr espond to it and lead to the change of structures.A fter years of studying on the self-assembly behavior of Au I -thiolate coordination polymer,w er ealize that it is very promising for it to develop into ah ighly dynamic system to construct unprecedented complex structuresa nd show environmental adaptions.

Reactions coupled self‐assembly represents a step forward towards biomimetic behavior in the field of supramolecular research. Here, two pH‐dependent reactions of thiol‐disulfide exchange and ligand exchange were used to couple with the self‐assembly of an AuI‐thiolate coordination polymer consisting of two ligands. Thanks to the comparable rates between the reactions and self‐assembly, the compositions of the assemblies change continuously with time, resulting in a highly dynamic assembly process and spatially inhomogeneous structure that are very common in life systems but cannot be easily obtained with one‐pot artificial methods.

Homogeneous 2D lamellar assemblies of Au thiolate coordination polymer (ATCP) were obtained by two-ligand co-assembly. The orbital levels and the bandgap of the 2D Au -S network in the centre of the lamellae can be continuously tuned by means of the capping ligands on both sides, to give a new type of inorganic-organic composite semiconductor, the band structure of which can be easily tuned by low-temperature solution-phase co-assembly. Furthermore, the chemical reactivity of these ATCP co-assemblies also proved to be strongly dependent on the organic substituents, with well-tuneable transformation rates to gold nanoparticles. Apparently, this is the first work to demonstrate how organic substituents can continuously tune the electron band structure and chemical reactivity of inorganic atomic layers of semiconductor through co-assembly.

The modification of inorganic two‐dimensional (2D) materials with organic functional motifs is in high demand for the optimization of their properties, but it is still a daunting challenge. Organic metal chalcogenides (OMCs) are a type of newly emerging 2D materials, with metal chalcogenide layers covalently anchored by long‐range ordered organic functional motifs, these materials are extremely desirable but impossible to realize by traditional methods. Both the inorganic layer and organic functional motifs of OMCs are highly designable and thus provide this type of 2D materials with enormous variety in terms of their structure and properties. This Minireview aims to review the latest developments in OMCs and their bulk precursors. Firstly, the structure types of the bulk precursors for OMCs are introduced. Second, the synthesis and applications of OMC 2D materials in photoelectricity, catalysis, sensors, and energy transfer are explored. Finally, the challenges and perspectives for future research on OMCs are discussed.
