“…type I PLs are neat liquids consisting of molecules that themselves form permanent pores in the liquid state; type II PLs are based on hosts molecules with permanent intrinsic pores dissolved in a liquid solvent that is excluded from the pores; and type III PLs, which contain a porous framework nanoparticle homogeneously dispersed in a liquid solvent in which the solvent molecules are sterically hindered from entering the pores. 2,31,48,49…”

Ionic Covalent Organic Frameworks for Energy Devices

Covalent organic frameworks (COFs) are a class of porous crystalline materials whose facile preparation, functionality, and modularity have led to their becoming powerful platforms for the development of molecular devices in many fields of (bio)engineering, such as energy storage, environmental remediation, drug delivery, and catalysis. In particular, ionic COFs (iCOFs) are highly useful for constructing energy devices, as their ionic functional groups can transport ions efficiently, and the nonlabile and highly ordered all‐covalent pore structures of their backbones provide ideal pathways for long‐term ionic transport under harsh electrochemical conditions. Here, current research progress on the use of iCOFs for energy devices, specifically lithium‐based batteries and fuel cells, is reviewed in terms of iCOF backbone‐design strategies, synthetic approaches, properties, engineering techniques, and applications. iCOFs are categorized as anionic COFs or cationic COFs, and how each of these types of iCOFs transport lithium ions, protons, or hydroxides is illustrated. Finally, the current challenges to and future opportunities for the utilization of iCOFs in energy devices are described. This review will therefore serve as a useful reference on state‐of‐the‐art iCOF design and application strategies focusing on energy devices.

“…Over the past decade, crystalline metal organic framework (MOF) membranes that exhibit inherently uniform and ordered sub-nanometer pores, which just located between the diameters of water molecules (0.28 nm) and common hydrated ions (≥0.66 nm), have been widely applied in water-salt separation. [7,8] Up to now, a series of continuous MOF membranes (like UiO-66, [9] MOF-303, [10] ZIF-8, [11] etc.) have been fabricated through solvothermal synthesis or layer-by-layer self-assembly and showed high rejections toward multivalent ion (≥90% for Na 2 SO 4 ).…”

Ultrafast Interfacial Self‐Assembly toward Supramolecular Metal‐Organic Films for Water Desalination

et al. 2022

Supramolecular metal‐organic materials are considered as the ideal candidates for membrane fabrication due to their excellent film forming characteristics, diverse metal centers and ligand sources, and designable structure and function. However, it remains challenging to rapidly construct highly permeable supramolecular metal‐organic membranes with high salt rejection. Herein, a novel ultrafast interfacial self‐assembly strategy to prepare supramolecular metal‐organic films through the strong coordination interaction between highly active 1,3,5‐triformylphloroglucinol (TFP) ligands and Fe3+, Sc3+, or Cu2+ at the organic–aqueous interface is reported. Benefiting from the self‐completing and self‐limiting characteristics of this interfacial self‐assembly, the new kind of supramolecular membrane with optimized composition can be assembled within 3.5 min and exhibits ultrathin, dense, defect‐free features, and thus shows an excellent water permeance (21.5 L m–2 h–1 bar–1) with a high Na2SO4 rejection above 95%, which outperforms almost all of the non‐polyamide membranes and commercially available nanofiltration membranes. This strong‐coordination interfacial self‐assembly method will open up a new way for the development of functional metal‐organic supramolecular films for high‐performance membrane separation and beyond.
