    Two-dimensional layered materials, represented by graphene, exhibit remarkable electron delocalization behavior due to their unique intra-layer atomic connection, which leads to outstanding physical and chemical properties
    Clusters have a definite number of atoms and a definite structure, and are a kind of condensed matter between atoms/molecules and nanocrystals.
    The sub-nanometer size of clusters enables single-molecule-level forces to dominate their self-assembly behavior.
    , which can be used as "super atoms" to construct a new sub-nanoscale low-dimensional material system

    The electronic structure and chemical properties of clusters are similar to those of atoms/molecules.
    Cluster assemblies are a class of "super molecules" in which electrons may be shared by multiple clusters.
    For highly ordered two-dimensional cluster assemblies,
    Delocalized behavior of electrons between clusters with the same chemical environment may lead to unusual electronic structures and catalytic properties

    Schematic diagram of the cluster alkene structure

    Based on this, Wang Xun's group from the Department of Chemistry, Tsinghua University reported for the first time a new class of graphene-like materials based on polymetallic oxygen clusters (POMs) - "cluster alkene-like"
    Different from the previous two-dimensional material systems that use atoms and molecules as structural units, this cluster alkene uses sub-nanometer-scale clusters as structural units to construct a new type of sub-nanometer two-dimensional material system

    The cluster alkenes showed great improvement in catalytic activity and stability for the epoxidation of olefins, and their turnover frequency (TOF) was 76.
    5 times higher than that of the unassembled clusters

    The discrete Fourier transform (DFT) calculation results show that the electron delocalization behavior between clusters effectively reduces the activation energy of the material participating in the redox reaction, resulting in a significant improvement in the catalytic activity

    Thirteen different element-substituted Keggin-type clusters can be used for the construction of cluster alkenes

    This study reveals the unique electronic structure, outstanding catalytic properties and good structural universality of clustered ene-like materials, which is expected to inspire the design and synthesis of new cluster-based materials


    The work was published in Nature Chemistry with the title of "Self-assembly of polyoxometalate clusters into two-dimensional clusterphene structures featuring hexagonal pores".
    The first author of the paper is Liu Qingda, a 16th-level doctoral student in the Department of Chemistry, Tsinghua University.
    The author is Professor Wang Xun of the Department of Chemistry

    The research was supported by the National Natural Science Foundation of China, the key research and development projects of the Ministry of Science and Technology, and the Scientific Exploration Award
