Hydrogen-bonded organic frameworks (HOFs), self-assembled from strategically pre-designed molecular tectons with complementary hydrogen-bonding patterns, are rapidly evolving into a novel and important class of porous materials. In addition to their common features shared with other functionalized porous materials constructed from modular building blocks, the intrinsically flexible and reversible H-bonding connections endow HOFs with straightforward purification procedures, high crystallinity, solution processability, and recyclability. These unique advantages of HOFs have attracted considerable attention across a broad range of fields, including gas adsorption and separation, catalysis, chemical sensing, and electrical and optical materials. However, the relatively weak H-bonding interactions within HOFs can potentially limit their stability and potential use in further applications. To that end, this Perspective highlights recent advances in the development of chemically and thermally robust HOF materials and systematically discusses relevant design rules and synthesis strategies to access highly stable HOFs.

of gases on solid surfaces. [9] This understanding aided the pioneering development of the first preconcentrator in 1969 by Dave et al. [10] This first preconcentrator utilized a polymer as the material for adsorption and desorption. Later, the first carbonaceous preconcentrator was developed in 1975 by Russell et al. [11] Until 1979, most preconcentration research relied on large instrumentation for analyte detection. However, in 1979, the development of the first micro gas chromatography (μGC) demonstrated that miniature detection methods are also possible. [12] The term "preconcentrator" was not used until 1989 by Thomas et al. [13] Later, the usability of oxide materials for preconcentration was explored; Casalnuovo et al. reported a SiO 2 based preconcentrator in 2001. [14] Ueno et al. introduced a metal-organic framework (MOF) based preconcentrator in 2007. [15] These major advances in preconcentrator development are shown in a timeline in Figure 1. The number of publications containing the term "gas preconcentrator," "gas pre concentrator," "gas pre-concentrator," "VOC preconcentrator" over time since 1989 is shown in Figure 2.In this review, recent developments of gas preconcentrators, preconcentrator materials, and preconcentration techniques are summarized. Different materials, their recent uses, limitations, and future potential are reviewed and discussed.

“…One of the major advances in crystal engineering chemistry over the last three decades has been the development of systematic modulation methods to construct highly porous crystalline solids with predictable structures [1][2][3]. The resulting materials are conventionally divided into the separate classes of metal-organic frameworks (MOFs) [4][5][6][7], covalent organic frameworks (COFs) [8][9][10], and hydrogen-bonded organic frameworks (HOFs) [11][12][13][14].…”

The development of hydrogen-bonded organic frameworks (HOFs) with predictable topologies and robust structures for targeted functionality was initially hindered by the relatively weak H-bonding interactions as many HOFs would collapse upon guest solvent removal. Recently, the design of tectons with large π-conjugated systems that form intermolecular shape-fitted π-π stacking interactions has proven to be an effective strategy to create chemically and thermally stable HOFs. More importantly, these HOFs with large π-conjugated tectons exhibit accelerated redox hopping processes due to more favorable through-space orbital overlap interactions. These intrinsic photoelectric properties render HOFs an appealing and unique class of photoactive and electroactive porous materials for catalysis, sensing, and biomedical applications. Based on shape-fitted π-π stacking strategy, various robust photoactive and electroactive HOFs have been built from tectons containing both photosensitive or redox-active organic cores and hydrogen bonding sites. This review summarizes the recent advancements, including synthetic methods and diverse applications, in the development of photo-and electro-active HOFs. Considering the numerous photo-and electro-active organic units available, as well as the virtually unlimited potential combinations of organic cores and hydrogen bonding sites, we anticipate that this review will inspire scientists in a range of disciplines, ranging from porous materials to organic photoelectric materials and catalysis scientists, to further explore functional photo-and electro-active HOF materials.
