《Magnetic covalent organic framework as platform for high-performance extraction of Cr(VI) and bisphenol A from aqueous solution》 was published in Journal of Hazardous Materials in 2020. These research results belong to Zhong, Xin; Lu, Zhipeng; Liang, Wen; Hu, Baowei. Name: 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde The article mentions the following:

The magnetic covalent organic framework with β-ketoenamine linkage (Fe3O4@COF(TpPa-1)) was fabricated by the hydrothermal method. The obtained Fe3O4@TpPa-1 integrated four advantages, namely easy preparation, high stability, excellent adsorption performance (485.2 m2/g) and good recoverability (19.5 emu/g), which enabled it an ideal sorbent for wastewater treatment. Fe3O4@TpPa-1 exhibited excellent adsorption capacities for Cr (VI) (245.45 mg/g) and bisphenol A (1220.97 mg/g). The adsorption kinetics and isotherms were in alignment to the pseudo-second-order and Langmuir model, resp. After five times cycles, the adsorption capacity of Fe3O4@TpPa-1 still retained at a high level. According to Materials Studio simulation and XPS anal., the adsorption mechanism was attributed to the presence of the homogeneously distributed imine and carbonyl functional groups in the framework of TpPa-1, allowing them to serve as platforms for anchoring heavy metals and organic pollutants. Besides, the hydrophobic skeleton structures of TpPa-1 endowed them good adsorption performance towards organic pollutants via hydrogen -bonding (NH…O…HO) and π-π interaction. Therefore, the recyclable Fe3O4@TpPa-1 showed a broad application prospects in environmental remediation. The results came from multiple reactions, including the reaction of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Name: 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde)

The author of 《Ionic liquid as a green solvent for ionothermal synthesis of 2D keto-enamine-linked covalent organic frameworks》 were Dong, Bin; Wang, Wen-Jing; Pan, Wei; Kang, Guo-Jun. And the article was published in Materials Chemistry and Physics in 2019. COA of Formula: C9H6O6 The author mentioned the following in the article:

Covalent organic frameworks (COFs) are usually synthesized under solvothermal conditions in a mixture of high-boiling organic solvents in a sealed system. By using a room temperature ionic liquid (IL) as a solvent, we presented the preparation of two-dimensional (2D) keto-enamine-linked COFs in an open container at ambient pressure. The as-synthesized 2D keto-enamine-linked COFs have ordered open channels and so the IL can be completely removed from the pores to provide the sole formation of crystalline 2D COFs. Not only the imidazolium-based IL acted as both solvent and catalyst, it was also recycled for further use without activity loss. The experimental part of the paper was very detailed, including the reaction process of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4COA of Formula: C9H6O6)

And the article was published in ACS Applied Materials & Interfaces in 2019. Electric Literature of C9H6O6 The author mentioned the following in the article:

There are several researches on the preparation and application of hydrazone-linked covalent organic frameworks (COFs), and all of them generally necessitate rigid aromatic amines. Herein, we report a strategy for design and synthesis of COF with flexible alkyl amine as a building block and intramol. hydrogen bonding as a knot in the network. The proof-of-concept design was demonstrated by exploring 1,3,5-triformylphloroglucinol and oxalyldihydrazide (ODH) as precursors to synthesize a novel COF material (TpODH), in which different organic building units are combined through hydrazone bonds to form two-dimensional porous frameworks. It should be pointed that irreversible enol-to-keto tautomerism and intramol. N-H···O=C hydrogen bonding of TpODH would enhance the crystallinity and chem. stability, leading to large sp. surface area of 835 m2 g-1. However, another COF synthesized with 1,3,5-triformylbenzene and ODH exhibited less crystallinity and low special surface area (94 m2 g-1). Representatively, the resulting TpODH afforded Cu(II) and Hg(II) capacities of 324 and 1692 mg g-1, resp., which exceeded that of most COFs previously reported. Moreover, the Fourier-transform IR and XPS spectra analyses were taken to demonstrate the adsorption mechanism. These results suggested that the materials could be applied to the removal of metallic ions in the future. In the experiment, the researchers used many compounds, for example, 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Electric Literature of C9H6O6)

In 2019,Journal of Membrane Science included an article by Shi, Xiansong; Xiao, Ankang; Zhang, Chenxu; Wang, Yong. Reference of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde. The article was titled 《Growing covalent organic frameworks on porous substrates for molecule-sieving membranes with pores tunable from ultra- to nanofiltration》. The information in the text is summarized as follows:

Crystalline imine-based covalent organic frameworks (COFs) have attracted great interest as next-generation water treatment materials owning to their numerous merits. The construction of COF layers with tunable pore sizes ranging from meso- to micropores, which can significantly broaden the membrane selectivity from ultra- (UF) to nanofiltration (NF), has remained unexplored. Herein, we demonstrate the controllable solvothermal synthesis of COF layers with adjustable pore sizes on anodic aluminum oxide (AAO) substrates. With rising synthesis duration the modulation on pore sizes of AAO supports can be achieved till the formation of continuous COF layers, leading to a gradually enhanced selectivity. Importantly, the synthesized microporous COFs shrink the pore sizes of AAO substrates and provide addnl. nanochannels for water transporting, eventuating in a ∼2-9 times higher permeance than other reported UF membranes with comparable rejections. Once forming continuous COF layers, more rigid selectivities based on COF inherent nanochannels (∼1.83 nm) can be realized with capacities of removing dyes from water or organic solvent. This work provides a facile methodol. to construct COF-based membranes with broadly tunable separation performance, recommending the membranes for removing targeted mols. including proteins, nanoparticles, and dyes. In the experiment, the researchers used 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Reference of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde)
