Subcomponent self-assembly is the most convenient and effective method to construct diverse metal-organic supramolecular architectures. It has become a powerful research tool for assembling rapidly together through simple building blocks via formation of covalent bonds around metal ions. This review focuses on the introduction of several metal-organic supramolecular systems based on subcomponent self-assembly, including helical structures, tetrahedral structures, hexahedral structures and octahedral structures. The unique chemical microenvironment which is derived from the internal cavities of these supramolecular structures can be used for guest recognition, protection, catalysis and extraction. Finally, the future development of this field is prospected.
Key words: subcomponent self-assembly, metal-organic supramolecular system, molecular cage, guest recognition, research progress
