Promoting photoswitching in mismatching mixed-linker multivariate Zr MOFs.

Multivariate metal-organic frameworks (MTV MOFs) have emerged as promising materials due to their ability to combine properties that enhance features beyond those of their pristine counterparts. Despite the potential for tailoring electronic properties through structural distortions and defects introduced by linkers of variable lengths, examples remain scarce, and information on the electronic structure is limited. Here, we present the multivariate mismatching linker approach to generate photoswitching nanoparticulated MOFs with variable lattice parameters and porosity features controlled by mixed-linker composition.

Fluorination of antimonene hexagons.

Fluorination of two-dimensional (2D) antimonene hexagons synthesized through a colloidal bottom-up approach has been explored using microwave-induced plasma and reactive ion etching fluorination strategies through the generation of CF. The stability of the fluorine bond has been corroborated through DFT calculations. This work paves the way for further halogen-derivative modifications of heavy 2D pnictogens.

On the Origin of the Above-Room-Temperature Magnetism in the 2D van der Waals Ferromagnet FeGaTe.

2D magnetic materials have attracted growing interest driven by their unique properties and potential applications. However, the scarcity of systems exhibiting magnetism at room temperature has limited their practical implementation into functional devices. Here we focus on the van der Waals ferromagnet FeGaTe, which exhibits above-room-temperature magnetism ( = 350-380 K) and strong perpendicular anisotropy.

Exploring Spin-Phonon Coupling in Magnetic 2D Metal-Organic Frameworks.

Layered magnetic metal-organic frameworks (MOFs) are an emerging class of materials that can combine the advantages of both MOFs and 2D magnetic crystals. The recent discovery of large coercivity and long-range magnetic ordering up to 515 K in a layered MOF of general formula MCl(pyz) (M = transition metal, pyz = pyrazine) offers an exciting versatile platform to achieve high-T magnetism at the 2D limit. In this work, we investigate the exfoliation feasibility down to the monolayer of VCl(pyz) and CrCl(pyz) by means of first-principles calculations.
