The article was titled 《Installing earth-abundant metal active centers to covalent organic frameworks for efficient heterogeneous photocatalytic CO2 reduction》. The information in the text is summarized as follows:

Photocatalytic conversion of CO2 into energy carriers has been recognized as a highly promising strategy for achieving the virtuous carbon cycle in nature. The realization of this process depends on an efficient catalyst to reduce the reaction barrier. Herein, we report a series of transition metal ion modified crystalline covalent organic frameworks (COFs) for the heterogeneous photocatalytic reduction of CO2. By coordinating different kinds of open metal active species into COFs, the resultant DQTP (2,6-diaminoanthraquinone – 2,4,6-triformylphloroglucinol) COF-M (M = Co/Ni/Zn) exerts a strong influence on the activity and selectivity of products (CO or HCOOH). Significantly, DQTP COF-Co exhibits a high CO production rate of 1.02 × 103 μmol h-1 g-1, while DQTP COF-Zn has a high selectivity (90% over CO) for formic acid generation (152.5 μmol h-1 g-1). This work highlights the great potential of using stable COFs as platforms to anchor earth-abundant metal active sites for heterogeneous CO2 reduction 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)

And the article was published in ACS Applied Materials & Interfaces in 2019. Quality Control of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde The author mentioned the following in the article:

Covalent organic frameworks (COFs) are penetrated with uniform and ordered nanopores, implying their great potential in mol./ion separations As an imine-linked, stable COF, TpPa-1 is receiving tremendous interest for mol. sieving membranes. Theor., atomically thin TpPa-1 monolayers exhibit extremely high water permeance but unfortunately no rejection to ions because of its large pore size (∼1.58 nm). The COF monolayers tend to stack to form laminated multi-layers, but how this stacking influences water transport and ion rejections remains unknown. Herein, we investigate the transport behavior of water and salt ions through multi-layered TpPa-1 COFs by nonequilibrium mol. dynamics simulations. By analyzing both the interfacial and interior resistance for water transport, we reveal that with rising stacking number of COF multi-layers exhibit increasing ion rejections at the expense of water permeance. More importantly, stacking in the offset eclipsed fashion significantly reduces the equivalent pore size of COF multi-layers to 0.89 nm, and ion rejection is correspondingly increased. Remarkably, 25 COF monolayers stacked in this fashion give 100% MgCl2 rejection, whereas water permeance remains 1 to 2 orders of magnitude higher than that of com. nanofiltration membranes. This work demonstrates the rational design of fast membranes for desalination by tailoring stacking number and fashion of the COF monolayers. In the experiment, the researchers used many compounds, for example, 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Quality Control of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde)

HPLC of Formula: 34374-88-4This research focused ontransformation covalent organic framework proton conductive electrolyte; covalent organic frameworks; fuel cells; ionic frameworks; organic gel; proton conductors. The article conveys some information:

We report the rational design and implementation of a new class of gel guest-assisted, ionic covalent organic framework (COF) membranes that exhibit superior H+ conduction. The as-synthesized COFs are postmodified via a lithiation (or sodiation) treatment. The hydrophilic Li or Na ions in the COFs form a dense and extensive hydrogen-bonding network of H2O mols. with mobile H+ at the periphery, thereby transforming COFs into H+ conductors. Then, the ionic COFs are assembled into a flexible H+ conductor membrane via a gelation process, where the organic gel provides both mech. strength and addnl. H+ carriers for fast H+ conduction. The final COF-based membrane exhibits an excellent H+ conductivity of 1.3 × 10-1 S cm-1 at 313 K and 98% relative humidity, which are the highest values of the COF-based H+ conductors reported until now and are even comparable with those of the typical com. Nafion membrane. We anticipate that the two-in-one strategy would open up a porous COF-driven new mol. framework and membrane architectural design/opportunity for development of next-generation ionic conductors.

The article was titled 《Weakly Humidity-Dependent Proton-Conducting COF Membranes》.Application In Synthesis of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde The article contains the following contents:

State-of-the-art proton exchange membranes (PEMs) often suffer from significantly reduced conductivity under low relative humidity, hampering their efficient application in fuel cells. Covalent organic frameworks (COFs) with pre-designable and well-defined structures hold promise to cope with the above challenge. However, fabricating defect-free, robust COF membranes proves an extremely difficult task due to the poor processability of COF materials. Herein, a bottom-up approach is developed to synthesize intrinsic proton-conducting COF (IPC-COF) nanosheets (NUS-9) in aqueous solutions via diffusion and solvent co-mediated modulation, enabling a controlled nucleation and in-plane-dominated IPC-COF growth. These nanosheets allow the facile fabrication of IPC-COF membranes. IPC-COF membranes with crystalline, rigid ion nanochannels exhibit a weakly humidity-dependent conductivity over a wide range of humidity (30-98%), 1-2 orders of magnitude higher than that of benchmark PEMs, and a prominent fuel cell performance of 0.93 W cm-2 at 35% RH and 80 °C arising from superior water retention and Grotthuss mechanism-dominated proton conduction.

The article was titled 《Enabling Covalent Organic Framework Nanofilms for Molecular Separation: Perforated Polymer-Assisted Transfer》. The information in the text is summarized as follows:

Covalent organic frameworks (COFs) with ordered arrays of sub-2 nm regular pores are drawing increasing attention in membrane separation, and it remains highly desirable for effective and controllable strategies to fabricate COF-based membranes. Herein, we demonstrate a perforated polymer-assisted transfer strategy enabling COF nanofilms for mol. separation Solvothermal synthesis is used for the confined growth of TpPa, a stable, imine-linked COF, on the smooth surfaces of silicon substrates. Continuous, crystalline COF nanofilms are obtained, and their thicknesses are tunable in the range from a few tens to several hundred nanometers depending on monomer concentrations and reaction time. A block copolymer layer is coated on the COF nanofilms, which is then perforated to produce interconnected mesopores by the mechanism of selective swelling-induced pore generation. The perforated polymer coating functions as a protective but permeable layer enabling the easy transfer of the COF nanofilm onto porous substrates. Thus, we obtain a new type of composite membranes with the microporous COF nanofilm as the selective layer, sandwiched between the macroporous substrate and the mesoporous protective layer. The composite membranes exhibit good separation performances with water permeance up to ∼51 L m-2 h-1 bar-1 and high rejection rates to various dyes. This work demonstrates a new method to prepare COF-based membranes for mol. separation, and the invented perforated polymer-assisted transfer technol. is expected to find applications in transferring other ultrathin materials to demanded substrates.

And the article was published in Advanced Energy Materials in 2019. Electric Literature of C9H6O6 The author mentioned the following in the article:

Adsorption-based cooling systems, which can be driven by waste heat and solar energy, are promising alternatives to conventional, compression-based cooling systems, as they demand less energy and emit less CO2. The performance of adsorption-based cooling systems relates directly to the performance of the working pairs (sorbent-water). Accordingly, improvement of these systems relies on the continual discovery of new sorbents that enable greater mass exchange while requiring less energy for regeneration. Here, it is proposed that covalent-organic frameworks (COFs) can replace traditional sorbents for adsorption-based cooling. In tests mimicking standard operating conditions for industry, the imine-based COF TpPa-1 exhibits a regeneration temperature below 65°C and a cooling coefficient of performance of 0.77 – values which are comparable to those reported for the best metal-organic framework sorbents described to date. Moreover, TpPa-1 exhibits a photothermal effect and can be regenerated by visible light, thereby opening the possibility for its use in solar-driven cooling.

《MOF@COFs with Strong Multiemission for Differentiation and Ratiometric Fluorescence Detection》 was written by Wang, Xin-Yao; Yin, Hua-Qing; Yin, Xue-Bo. Product Details of 34374-88-4 And the article was included in ACS Applied Materials & Interfaces in 2020. The article conveys some information:

Aggregation-caused quenching (ACQ) is often observed in covalent organic frameworks (COFs) for their low emission. Here, we propose that limited COF layers form on UiO-66 to eliminate the ACQ by the formation of UiO@COF composites. UiO-66 is selected because this metal-organic framework (MOF) is easily prepared in nanosize with Zr4+ ion and 2-aminoterephthalic acid (BDC-NH2). The high affinity of the Zr4+ ion to phosphate species improves sensing selectivity. The surface -NH2 reacts with 2,4,6-triformylphloroglucinol (Tp) to integrate COF1 and COF2, which are prepared with Tp and phenylenediamine or tetraamino-tetraphenylethylene, resp. The hydrogen bond formed between the hydroxyl group in Tp and imine nitrogen realizes excited-state intramol. proton transfer; therefore, multiemission is observed from the enol and keto states of the COFs and UiO-66 at 360, 470, and 613 nm for UiO@COF1 and at 370, 470, and 572 nm for UiO@COF2. When phosphate ion is added in the composites, the emissions from the COFs keep stable, while that from UiO-66 is enhanced. However, adenosine-5′-triphosphate (ATP) improves the emissions from UiO-66 and COF’s enol state, but that from the keto state keeps stable. The differentiation and ratiometric fluorescence detection of ATP and phosphate ion are therefore realized with the multiemission, the affinity of Zr4+ ions, and the structural selectivity of the COFs. Thus, UiO@COF is a novel strategy to integrate multiemission, affinity, and structural selectivity to improve the sensing performance for differentiation and ratiometric detection.

The article conveys some information:

Heavy metal ion removal from wastewater has gained intense attention due to metal toxicity, bioaccumulation tendency, and persistence. Adsorption is a most promise method because of its simplicity and efficiency. This work reports preparation of an EDTA-functionalized covalent organic framework (COF) for heavy metal ion removal. A COF, TpPa-NO2, was reduced to TpPa-NH2 using a Na2S2O4 reductant, then EDTA dianhydride was grafted on the TpPa-NH2 to form TpPa-NH2@EDTA via post-modification. COF morphol. and structure remained unchanged after post-modification. TpPa-NH2@EDTA displayed excellent heavy metal ion adsorption performance (e.g., soft Lewis acids [Ag+, Pd2+], hard Lewis acids [Fe3+, Cr3+], borderline Lewis acids [Cu2+, Ni2+]) with removal efficiencies all >85% within 5 min due to the EDTA strong chelation effect. TpPa-NH2@EDTA also showed high adsorption ability in a pH ≥3 environment with an adsorption capacity >50 mg/g for six representative heavy metal ions. This work provided an idea to use COF materials to remove heavy metal ions from wastewater.

The article was titled 《An enhanced proton conductivity and reduced methanol permeability composite membrane prepared by sulfonated covalent organic nanosheets/Nafion》. The information in the text is summarized as follows:

Sulfonated covalent organic nanosheets (SCONs) with a functional group (-SO3H) are effective at reducing ion channels length and facilitating proton diffusion, indicating the potential advantage of SCONs in application for proton exchange membranes (PEMs). In this study, Nafion-SCONs composite membranes were prepared by introducing SCONs into a Nafion membrane. The incorporation of SCONs not only improved proton conductivity, but also suppressed methanol permeability. This was due to the even distribution of ion channels, formed by strong electrostatic interaction between the well dispersed SCONs and Nafion polymer mols. Notably, Nafion-SCONs-0.6 was the best choice of composite membranes. It exhibited enhanced performance, such as high conductivity and low methanol permeability. The direct methanol fuel cell (DMFC) with Nafion-SCONs-0.6 membrane also showed higher power d. (118.2 mW cm-2), which was 44% higher than the cell comprised of Nafion membrane (81.9 mW cm-2) in 2 M methanol at 60°. These results enabled to work on building composite membranes with enhanced properties, made from nanomaterials and polymer mols.
