“…Furthermore, Xia et al successfully synthesized two kinds of COF-based paper composites (COF-Paper1 and COF-Paper2) with exceptional solid-state luminescence via an in situ growth method. [64] Interestingly, they could be employed as turn-off fluorescence sensors for detecting Fe 3 + and UO 2 2 + visually. Significantly, it demonstrated a low sensing limit (5.6 ng cm À 2 for Fe 3 + and 27 ng cm À 2 for UO 2 2 +…”

Hydrazone‐linked covalent organic frameworks (COFs) with structural flexibility, heteroatomic sites, post‐modification ability and high hydrolytic stability have attracted great attention from scientific community. Hydrazone‐linked COFs, as a subclass of Schiff‐base COFs, was firstly reported in 2011 by Yaghi’s group and later witnessed prosperous development in various aspects. Their adjustable structures, precise pore channels and plentiful heteroatomic sites of hydrazone‐linked structures possess much potential in diverse applications, for example, adsorption/separation, chemical sensing, catalysis and energy storage, etc. Up to date, the systematic reviews about the reported hydrazone‐linked COFs are still rare. Therefore, in this review, we will summarize their preparation methods, characteristics and related applications, and discuss the opportunity or challenge of hydrazone‐linked COFs. We hope this review could provide new insights about hydrazone‐linked COFs for exploring more appealing functions or applications.

“…It is worth noting that in the presence of surfactant, the dispersion of COF in aqueous solution is improved, and the detection sensitivity can be improved by adjusting K SV . Xia et al 36 used an in-situ growth method to prepare two 2D COF paper composites (COF-Paper1 and COF-Paper2), which were used as fluorescence sensing materials to detect Fe 3+ visually. (Figure 4) XPS and FT-IR indicated that the obtained COF backbone had abundant chelating units, which could coordinate with Fe 3+ .…”

With the development of industrialization, chemical detection plays a vital role in many fields. As a new type of porous material, covalent organic frameworks (COF's) possess the characteristics of huge specific surface area, low density, great stability, and adjustable pore size. These characteristics make it a great prospect for chemical detection. In the article, we mainly show how to design several analytic platforms to achieve precise target detection by utilizing the special properties of COF's, put forward the relevant mechanisms of successful detections, and analyze the related parameters of analyte detection performance. Finally, the current challenges of chemical detection based on COF's are presented, and we also prospect the future research directions.

“…Using these reactions, a variety of valuable chemical structures can be synthesized. Dha in the field of chemical testing [3] and materials chemistry is widely used [4,5]. For example, Yan and collaborators used Dha to design and synthesize Por-COFs with highly photosensitizing activity for photodynamic inactivation of bacteria through a coupling regulation strategy [6].…”

2,5-Dihydroxyterephthalendehyde (Dha) can be used as an intermediate in organic chemistry and synthetic materials, which can participate in a variety of chemical reactions. Through these reactions, a variety of valuable compounds can be synthesized. However, the existing synthesis methods are cumbersome, difficult to operate, and have low yields. Referring to the reported Dha synthesis process, we successfully synthesized Dha using inexpensive 1,4-dimethoxybenzene with simple steps. The correct structure was proved by Fourier transform infrared (FT-IR) spectroscopy, nuclear magnetic resonance (1H-NMR) hydrogen spectroscopy, and nuclear magnetic resonance (13C CP-MAS NMR) carbon spectroscopy, which provides a valuable reference for the synthesis of Dha.
