“…[ 44–46 ] PLGA as an anionic polypeptide with enriched carboxyl groups can competitively bind Zn 2+ with HmIM and form new ZnO coordination bonds. [ 47,48 ] The different coordination environments of Zn 2+ nodes on specific crystal facets may affect the adsorption of PLGA molecules; the low exposure area of metal nodes and high steric hindrance render it difficult for the coordination interaction between PLGA and Zn 2+ nodes. While increasing PLGA molecules, it will preferentially coordinate on the Zn 2+ nodes of other crystal facets and block the binding to the HmIM ligands, which triggers the crystal defect and causes the morphology evolution of biomacromolecules@MOFs.…”

Benefiting from the distinct structural features, metal-organic frameworks (MOFs) open new significant opportunities for biomacromolecule encapsulation to design biofunctional composites, whereas their biological activity and utilization efficiency remain challenging for the construction of advanced immunosensor. Herein, biomacromolecules are spatially encapsulated integration on the cavity of peptide-mediated MOFs with controllable nanoarchitectures, which amplifies the immunosensor signals via boosting bioactivity and utilization efficiency. Notably, the morphological evolution of MOFs composite including dodecahedrons, nanostars and flower-shaped nanostructures is achieved by introducing peptide surface modifier to trigger the coordination defects procedure. Nanostars are evidenced with the enhanced catalytic activity of biomacromolecules, which amplifies the recognition signal via regulating the pore channel and particle size of biomacromolecules@ MOFs composite, shortening the diffusion path of substrate molecules and promoting the interfacial contact. As proof-of-principle, imidacloprid is chosen as a model target to demonstrate the superiority of biomacromolecules@MOFs-based immunosensor. Combining the enhanced activity of biomacromolecules with size tunability of biomacromolecules@MOFs composite, 160-fold improvement in the sensitivity is obtained in comparison with the conventional enzyme-based immunoassay, paving the way for the employment of controllable nanostructures for high-sensitive biosensors.

“…Despite the fact that the main crystallization processes of coordination polymers are governed by similar rules, the detailed mechanism can be different owing to the complex topology, coordination bonds, and secondary building blocks of coordination polymers [94]. Ex situ and in situ characterizations and computer simulations have been employed to investigate and analyze the crystallization processes of several coordination polymers [94][95][96][97]. The results suggest that there are many kinds of prenucleation clusters (PNCs), transition phases, and actual second building units (SBUs) in the prenucleation and growth steps (Figure 1).…”

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.

“…Interfacial synthesis confines metal ions and organic ligands at the interface of two phases to form a thin sheet of MOFs. With the aid of non-destructive optical methods, it is possible to monitor the growth of the crystal interface and indicate the presence of a reversible transition layer at the growth interface, which provides guidance for the synthesis of MOFs [189,190] . Coordination reactions that typically occur at the interface of two phases have the advantage of large area, good size ratio and easy transfer to the device [191] .…”

As a new kind of organic-inorganic hybrid porous material, metal-organic frameworks (MOFs) exhibit a wide application prospect in gas storage and separation, catalysis and sensing due to their characteristics of large specific surface area, high porosity and coordination unsaturation. As more and more types of MOFs were reported, the synthetic strategies of MOFs-based materials have become a hot research topic. According to the morphological dimension, MOFs can be roughly divided into one-dimensional, two-dimensional and three-dimensional structures. Herein, we summarize the synthetic methods and principles of MOFs from multi-dimensional perspectives, and explore the growth mechanism of MOFs with different morphologies based on dynamic and thermodynamic tuning. Finally, based on the above summaries, the challenges and opportunities of MOFs in the future are discussed.
