“…Using ordered species to fill the connected vessels can be represented by filling a single-crystal lattice which describes the three-dimensional ordering of structural motifs of crystals. − However, this is generally difficult to realize experimentally because conucleation and growth inside the connected vessels usually lead to lattice domains which are confined to a short range, forming polyoriented domains (polycrystals) or nanosized domains (nanocrystals) (Figure S2). , It has been reported that a single crystal can incorporate discrete species inside, which means that it is possible to fill the single crystals across several branches of a specific type of the connected vessels, the connected spaces inside 3D networks. ,− By carefully controlling the crystallization kinetics, single crystals have been successfully grown inside templates with ordered porous structures. − In these cases, multiple channels are occupied by a single crystal. After careful surveying of these reports, we noticed that these single crystals could be distinguished into two types.…”

Connected vessel effects have been widely utilized from ancient times. It is quite interesting to know whether there are any special effects when single-crystal lattices fill the connected spaces inside 3D networks. In some single-crystal and 3D network pairs, there seems to exist a specific rule: when single-crystal lattices fill the connected spaces inside 3D networks, the front of the lattice in each channel is determined by the symmetrical center of the lattice structure. However, this needs to be validated by using various single-crystal lattice to fill the 3D networks with different compositions. Here we report a method to establish a gradient environment which can favor the formation of a micrometer-sized single crystal lattice across various 3D networks. The fronts of the filled lattices form the shapes which are the equilibrium shapes of the single crystals no matter what the single crystals or the 3D networks are, indicating the specific rule while the single-crystal lattices fill the 3D networks. The single crystals filled in the connected spaces inside 3D networks, which are functional materials, and had alternating properties, such as 4-fold higher electronic conductivity, which improve their performance in applications.

“…The encapsulation of networks can help to regulate the properties of monocrystalline coordination polymers. Bare or modified carbon nanotubes could be modified to allow coordination polymers to grow around [ 109 – 110 ]. This is used to form monocrystalline coordination polymers embedding a fast electron transfer route [ 110 ].…”

Various kinds of monocrystalline coordination polymers are available thanks to the rapid development of related synthetic strategies. The intrinsic properties of coordination polymers have been carefully investigated on the basis of the available monocrystalline samples. Regarding the great potential of coordination polymers in various fields, it becomes important to tailor the properties of coordination polymers to meet practical requirements, which sometimes cannot be achieved through molecular/crystal engineering. Nanoarchitectonics offer unique opportunities to manipulate the properties of materials through integration of the monocrystalline building blocks with other components. Recently, nanoarchitectonics has started to play a significant role in the field of coordination polymers. In this short review, we summarize recent advances in nanoarchitectures based on monocrystalline coordination polymers that are formed through confined assembly. We first discuss the crystallization of coordination polymer single crystals inside confined liquid networks or on substrates through assembly of nodes and ligands. Then, we discuss assembly of preformed coordination polymer single crystals inside confined liquid networks or on substrates. In each part, we discuss the properties of the coordination polymer single crystals as well as their performance in energy, environmental, and biomedical applications.

“…These composites are normally synthesized by mixing a specified amount of CNT with MOF precursors, followed by the in situ growth of MOF crystals. Nice typical images of a ZIF-8/CNT composite are represented in Figure , where a nonionic agent (PVP) was employed to change the crystal size of the MOF component …”

The development of materials and methods efficient for carbon capturing, methane storage, and selective separation of CO 2 and CH 4 from gas mixtures is a crucial approach to addressing the problems of these two greenhouse gases. In this regard, metal organic framework (MOF)-based composite materials are recognized as a promising class of materials, which could combine the advantages of MOFs and the other constituents to reduce their current drawbacks in the adsorption/separation systems. In this context, a series of MOF composites recently developed for CO 2 and CH 4 adsorption and their selective separation from gas mixtures are presented and discussed: MOF/carbon-based materials, MOF/Si-based composites, MOF mixed-matrix membranes, MOF/MOF, and MOF/metal oxide structures. Here, with an emphasis on the most recent signs of progress, we hope to shed a light on the MOF composites and assist future research to promote the performance of current composites and develop new MOF hybrid structures considering the proposed challenges.
