Porous organic materials offer vast future opportunities

Abstract

In light of the surging research on porous organic materials, we herein discuss the key issues of their porous structures, surface properties, and end functions. We also present an outlook on emerging opportunities, new applications, and data science-assisted materials discovery. Porous organic materials have diverse compositions and tunable pore sizes (Fig. 1), which have enabled a wide variety of applications including separation, filtration, storage, catalysis, and drug delivery. According to the International Union of Pure and Applied Chemistry definition, the pores in the porous organic materials are classified into micropores (<2 nm), mesopores (2-50 nm), and macropores (>50 nm). It is often beneficial for porous organic materials to possess hierarchical pores across multiple length scales. The size exclusion of these pores, as well as the physical and chemical interactions of molecules with pore surfaces, offer the porous organic materials tunable permeability and selectivity that are critical to their applications.

Extreme Biomimetics: Designing of the First Nanostructured 3D Spongin–Atacamite Composite and its Application

“…Their skeletal structural motifs match well with artificially designed bio-based porous organic materials (i.e., collagen, silk, chitosan, cellulose) [4][5][6][7][8][9][10] as well as with trends recognized for porous scaffolds design. [11,12] Previously, spongin-based templates have been used to produce 3D porous hydroxyapatite ceramics [13,14] including a calcination approach at remarkable 750 °C. [15] The exact composition of spongin is unknown; it has a collagen-based main structural motif of the proteinaceous origin but contains a significant amount of cysteine and halogenated (I, Br, Cl) amino acid residues.…”

Nanoporous Metal Phosphonate Hybrid Materials as a Novel Platform for Emerging Applications: A Critical Review

“…into three categories by their pore sizes, including micropores (<2 nm), mesopores (2-50 nm) and macropores (>50 nm). [8] Correspondingly, the pore walls include inorganic skeleton (e.g., zeolites, porous carbons, and mesoporous silica), the organic skeleton (e.g., porous polymers, organic porous cages, and supramolecular organic frameworks), and the hybrid skeleton (e.g., organic-inorganic hybrids and metal-organic frameworks (MOFs)). [4] Among these, porous organic-inorganic metal phosphonate hybrid materials have drawn a growing level of research interest due to their ability to integrate the advantages of both porous materials and periodic organic-inorganic skeleton structures.…”

Dual-functional ionic porous organic framework for palladium scavenging and heterogeneous catalysis

“…Porous organic frameworks (POFs) are an emerging class of porous materials demonstrating unique characteristics of large specific surface areas, tunable porosities, and high physical and chemical stability. [1][2][3][4][5] They are constructed by joining pure organic monomers via covalent bonds. From a synthetic point of view, numerous organic monomers and several organic reactions (e.g., condensation reactions, coupling reactions) can be applied in the synthesis of POFs.…”
