“…Fourier transform infrared (FTIR) spectra of ZrBTB and ZrBTB–SO 3 are shown in Figure c. Three major characteristic peaks of ZrBTB located at 1606, 1537, and 1413 cm –1 can be observed in both spectra, confirming the presence of O–C–O and aromatic CC bonds of ZrBTB in both MOFs before and after SALI . After the incorporation of sulfonate-based ligands, two additional peaks located at 1114 and 1042 cm –1 corresponding to the SO bond of sulfonate can be observed, , which verifies the presence of coordinated sulfoacetate ligands in ZrBTB–SO 3 .…”

“…After sonication for 5 min, the mixture was heated in an oven at 60 °C for 18 h. After cooling the mixture to room temperature (RT), 30 mL of fresh DMF was used to wash the solid three times to remove the unreacted chemicals. Afterward, the solvent-exchange process with acetone and the activation process were performed, similar to those reported previously; , the resulting solid was designated as “ZrBTB–SO 3 .…”

Polyaniline (PANI) is a conducting polymer with remarkable electrochemical performance for supercapacitors. On the other hand, materials with sulfonate groups, such as polystyrenesulfonate and Nafion, are commonly used as the dispersants to spatially separate the polymeric chains of PANI by means of the electrostatic interaction between the aniline unit and the negatively charged sulfonate. Herein, a two-dimensional (2D) zirconium-based metal−organic framework (MOF) with enriched sulfonate-based ligands postsynthetically coordinated onto its nodes, ZrBTB−SO 3 (BTB = 1,3,5-tri(4-carboxyphenyl)benzene), is utilized as the dispersant during the in situ polymerization of aniline; composites with various ratios between PANI and ZrBTB−SO 3 are thus synthesized. For comparison, the pristine 2D MOF without sulfonate groups is also subjected to the in situ polymerization to synthesize the PANI@ZrBTB composite. Crystallinity, porosity, morphology, elemental composition, and electrical conductivity of each composite are examined. These PANI-based materials are thereafter cast on the electrodes as thin films to investigate their electrochemical capacitive performances in acidic aqueous electrolytes. With the help of the negatively charged sulfonatefunctionalized 2D MOF sheets as the dispersant, the resulting PANI in the composite can achieve a specific capacitance of 515 F/g at a charge−discharge current of 0.5 mA/cm 2 , which is much higher than those achieved by the pristine PANI (230 F/g), PANI@ ZrBTB (137 F/g), and the physical mixture of PANI and ZrBTB−SO 3 (130 F/g). Findings here open numerous opportunities for utilizing such water-stable and sulfonate-functionalized 2D MOFs to spatially disperse various conducting polymers and boost their performances in a range of applications.

Ferromagnetism in 2D materials has attracted tremendous interest from the scientific community thanks to its potential for the design of magnetic materials with unique properties. The presence of a ferromagnetic element in a 2D material can improve the existing properties and offer new ones, giving rise to the development of manifold applications. This review focuses on recent advances and perspectives of 2D materials that bear at least one ferromagnetic element (iron, cobalt, nickel) as i) structural constituent, ii) dopant atom, or iii) adjacent atom through proximity effect. By describing in detail the magnetic properties that have emerged so far, their potential to form next‐generation 2D magnets is discussed. Moreover, the contribution of such 2D materials is analyzed in various applications (electrochemical, photochemical, optical, and electronic), aiming to explore further functionalities and capabilities of ferromagnetic elements, apart from their magnetic nature. Special attention is given to gadolinium and other rare earth elements that display a ferromagnetic order even at ultra‐low temperatures and form part of 2D structured materials, with particularly appealing properties deriving from their 4f electrons.
