Artificial light-harvesting systems(LHSs) have drawn increasing research interest in recent times due to the energy crisis worldwide. Concurrently, macrocycle-based host–guest interactions have played an important role in the development of supramolecular chemistry. In recent years, studies towards artificial LHSs driven by macrocycle-based host–guest interactions are gradually being disclosed. In this mini-review, we briefly introduce the burgeoning progress of artificial LHSs driven by host–guest interactions. We believe that an increasing number of reports of artificial LHSs driven by host–guest interactions will appear in the near future and will provide a viable alternative for the future production of renewable energy.

Two new bis-imidazolinium salts (4a, 4b) have been synthesized as precursors of N-heterocyclic carbenes (NHCs) from the commercially available (R)-2,2′-dihydroxy-1,1′-binaphthalene. The two bis-imidazolinium salts were used as efficient precursor of NHC ancillary ligands in the palladium-catalyzed Heck reaction. Good to excellent yields and high stereoselectivities were obtained with ethyl acrylate, acrylonitrile, and acrylamide as starting materials. The structure of bis-imidazolinium salt 4b was further characterized by single crystal X-ray diffraction analysis.

The rapid and precise fabrication of multiscale supramolecular assemblies using micro/nanofluidic techniques has emerged as a dynamic area of research in supramolecular chemistry, materials chemistry, and organic chemistry. This review summarizes the application of micro/nanofluidic techniques in constructing supramolecular assemblies, including nanoscale supramolecular assemblies such as macrocycles and cages, microscale supramolecular assemblies such as metal organic frameworks (MOFs) and covalent organic frameworks (COFs), and macroscale supramolecular assemblies such as supramolecular hydrogels. Compared to conventional synthesis methods, micro/nanofluidic techniques for the production of supramolecular assemblies have significant advantages, including enhanced safety, high reaction rates, improved selectivity/yield, and scalability. Additionally, micro/nanofluidic systems facilitate the creation of precisely controllable micro/nanoconfined environments, allowing for a unique flow behavior that improves our understanding of the supramolecular self-assembly process. Such systems may also lead to the development of novel supramolecular assemblies that differ from those generated via traditional methods.

由于具有三维空腔结构及良好的应用前景,穴醚逐渐成为超分子研究领域的热点之一.近年来,我们课题组设计合成了一系列基于双间苯-32-冠-10穴醚主体分子,并利用这些穴醚分子构筑了不同的超分子组装体.首先,将双硫代四硫富瓦烯(STTFS)引入到穴醚的第三个臂上,成功构筑了具有氧化还原响应性的穴醚主体分子.该穴醚与客体间的解离-穿环过程可以利用STTFS的氧化态来进行控制;其次,设计合成了两种含有P=O官能团桥连的穴醚,在固态结构中得到了近似线型和Z字型的不同超分子聚[2]准轮烷;最后,合成了具有两种不同性质空腔的柱[5]芳烃稠合穴醚主体分子,该穴醚通过正交作用同时络合两个不同的客体分子.基于两种不同主客体作用力,我们构筑了一种新型的超分子聚合物.以上研究为分子器件和超分子材料的进一步研究奠定了良好的基础.
