A series of supramolecular polymers based on direct coordination of metal ions to the cucurbit[n] urils with the aid of the outer-surface interactions of cucurbit[n] urils could become a new branch in Q s-based coordination chemistry. According to the characteristics of the outer-surface interactions of cucurbit[n] urils, they can be catalogued in: 1) electrodonating effect of the alkyl-substituted groups on the outer-surface of cucurbit[n] urils; 2) interactions between methine or methylene moieties on the outer-surface of cucurbit[n] urils and aromatic moiety of organic structure directing agents; 3) interactions between methine or methylene moieties on the outer-surface of cucurbit[n] urils as well as ion-dipole interactions between positive portal carbonyl carbon of cucurbit[n] urils and chloride anion from polychlorometallate anions; 4) coordination interaction between hydroxyl groups on the outer-surface of cucurbit[n] urils with metal ions. Based on the characteristics of the supramolecular coordination polymers, they have potential applications in the fields, such as absorption, analysis, separation, isolation, and so on.

Conductive polymer materials have electronic properties like metal and flexibility and processability as organic materials. They have promise in military, energy and biosensor applications. However, damaged electronic component can ruin the circuit board and paralyze the entire electronic device. Such a problem can be solved by using self-healing conductive materials, which are capable of repairing the damage like biological system.

Porphyrin arrays are multiporphyrinic systems which assembled either by bridging units or bonds. The electronic properties of porphyrin arrays depend on the bridging units and the bridging positions on porphyrins. In the last two decades, electronically interacting multiporphyrinic systems have been actively explored due to their potential applications in optoelectronic devices, sensors, photovoltaic devices, nonlinear optical materials, and photodynamic therapy pigments. Porphyrin arrays can be constructed by means of noncovalent bonds or covalent bonds, the former is easy but the assembled array is unstable while the latter is opposite. The Suzuki-Miyaura coupling reaction is classified as a coupling reaction where the coupling partners are a boronic acid or borate ester with a halide catalyzed by a palladium (0) complex. It is an efficient method to construct porphyrin arrays with diversity structures and different properties. In this review, the emphasis has been placed upon the progress in the construction of the porphyrin arrays via Suzuki-Miyaura reaction. At last, we prospect the development trend of constructing porphyrin arrays via Suzuki-Miyaura coupling reaction.

Supramolecular chemistry is originated from synthetic organic chemistry and host-guest chemistry and its development greatly relies on the advance of host-guest chemistry. Synthetic macrocyclic compounds as an important part of host-guest chemistry and supramolecular chemistry have been designed and synthesized to further construct organic functional materials. In the past few decades, scientists have investigated a variety of supramolecular host compounds, including crown ethers, cyclodexrins, calixarenes, cucurbiturils, and pillarenes (or pillar [n]arenes, n=5~15). In particular, pillarenes, which can be easily synthesized and functionalized, have gained great attention for their typically rigid pillar-shape architecture and unique physical and chemical properties. Meanwhile, pillarenes have made great additions to the development of organic functional materials and enriched the contents of supramolecular chemistry and nanoscience. To the best of our knowledge, these pillarene-based organic functional materials have been successfully applied to many different scientific fields including molecular recognition and self-assembly, bacteria and virus inhibition, detection of pesticide and heavy metal ions, stabilization of nanoparticles, optical sensing, catalysis, biological sensing, drug delivery and controlled release, and so on. In this review, we mainly focus on summarizing the research progress of pillarene-based organic functional materials and comment on the bright future of their potential applications.

Dynamic covalent macrocycles templated by organic molecules have been thoroughly reviewed. Organic templates have much larger sizes than metal ions, and therefore are suitable to template the formation of macrocycles with much larger cavity. Meanwhile, there are a variety of organic molecules, which may work as templates. Their structures can be tailor-made through various organic reactions. Out of many dynamic covalent bonds, there are three popular types which are often used to construct dynamic covalent macrocycles via template effect: disulfide, boronic ester, and imine. The reversibility of former two bonds can be switched on or off through changing the conditions. While imine bonds can be reduced to kinetically inert chemical bonds. Thus, the thermodynamically stable macrocycles in the presence of templates can be converted to the corresponding kinetically inert macrocycles, providing a new method for the preparation of macrocyclic hosts. In addition, the host-guest binding motifs based on dynamic covalent macrocycles can be used to construct more complex supramolecular architectures, for example, rotaxanes and catenanes.

Mechanically interlocked structures are a kind of supramolecular entities with unique properties. They have attracted much attention not only because of their fascinating aspect of topologies, but also due to their great potential applications in nanotechnology, biology, and material science, as well as important bases for the preparation of molecular machines. This article summarizes new progress in the preparation of rotaxanes, catenanes, and other mechanically interlocked structures assembled via coordination interactions, especially focuses on the examples using metal-mediated coordination interactions as building ways cooperating with host-guest chemistry. Because coordination bonds are easy bonding, dynamically reversible, and easily controllable, the usage of metal-mediated coordination for constructing mechanically interlocked structures can greatly improve the preparation efficiency, and benefit to realizing the reversible regulation of mechanically interlocked structures.
