“…To ascertain the surface chemistry of Co@MCTF, X-ray photoelectron spectroscopy (XPS) analysis was carried out, and the survey spectrum verified the presence of C, N, O, Fe, and Co (Figure a). The deconvoluted peaks of C 1s at 284.8 and 287.1 eV correspond to C–C, and CN, respectively, originating from the carbon present the N-rich triazine framework. , The peak at 288.7 eV corresponds to C–O and peak at 292.0 eV corresponds to the existence of π–π interaction, which confirms the chemical contact between the covalent triazine frameworks and also with Fe 3 O 4 NSs . Further, a carbidic metal (Co)-C peak was observed at 283.7 eV, indicating the interaction of the triazine framework with Co (Figure b) .…”

The present study describes a methodology to heterogenize metallic Co nanoparticles (NPs) on hollow Fe 3 O 4 nanospheres, surfacefunctionalized with a porous covalent triazine framework, leading to a magnetically separable catalyst that exhibits efficient catalytic activity in hydrogenation, ligand-free Buchwald-Hartwig N-arylation, and oxidation reactions. Here, the presence of a nitrogen-enriched porous structure is expected to provide potential interactions with active centers through coordination (M←N), enable the isolation of the entrapped catalytically active Co NPs, and prevent the possibility of sintering during catalytic reactions, resulting in structurally stable catalytic sites, which makes them recyclable without any loss in activity.

“…Due to the high electronegativity of TC containing benzene ring, binding energies of the three characteristic peaks including O1 peak at 529.7 eV (Ni–O), O2 peak at 531.5 eV (O–H), and O3 (physically/chemically adsorbed water on the surface of the samples) decreased after the adsorption of TC . In Figure d, the binding energy of the π–π peak shifted from 291.68 to 291.24 eV after adsorption of TC, indicating the presence of π–π interactions . In addition, the binding energy of the C–O(H) peak increased from 285.52 to 286.47 eV, indicating that hydrogen bonding was involved in the adsorption of TC.…”

The efficient removal of antibiotic residues from aqueous solution is very important for water security. Studies have found that adsorption is widely used for the removal of antibiotics due to its costeffectiveness, low energy consumption, simplicity of operation, and environmental friendliness. In this study, a novel magnetic porous carbon adsorbent (Ni-MPC-400) with a high adsorption capacity and saturation magnetization was synthesized via direct carbonization of Ni-MOF at 400 °C pyrolysis temperature and used to efficiently remove tetracycline from an aqueous solution. Adsorption experiments showed that Ni-MPC-400 exhibited excellent tetracycline adsorption capacity (441.51 mg•g −1 ) from the aqueous solution. Possible adsorption mechanisms were proposed through characterization and analysis. The adsorption mechanisms mainly involved π−π interactions, hydrogen bonding, metal−organic complexation, and pore filling effects. In addition, Ni-MPC-400 showed rapid and sufficient adsorption at a low concentration of tetracycline (5 mg•L −1 ) and good adsorption performance over a wide pH range. In addition, the material has been tested to have good immunity to interference and regenerative capacity, demonstrating a potential application in the removal of tetracycline contaminants from aqueous solutions.

Organic thin‐film transistors (OTFTs) as a vital component among transistors have shown great potential in smart sensing, flexible displays, and bionics due to their flexibility, biocompatibility, customizable chemical structures. Even though linear conjugated polymer semiconductors are common for constructing channel materials of OTFTs, advanced materials with high charge carrier mobility, tunable band structure, robust stability, and clear structure‐property relationship are indispensable for propelling the evolution of OTFTs. Two‐dimensional conjugated polymers (2DCPs), featured with conjugated lattice, tailorable skeletons, and functional porous structures, match aforementioned criteria closely. In this review, we firstly introduce the synthesis of 2DCP thin films, focusing on their characteristics compatible with the channels of OTFTs. Subsequently, the physics and operating mechanisms of OTFTs and the applications of 2DCPs in OTFTs are summarized in detail. Finally, the outlook and perspective in the field of OTFTs using 2DCPs are provided as well.
