We report the exploration of fluorescent nanoscale metal-organic frameworks (nMOF-253s) for highly selective and sensitive detection of Fe(2+) ions in aqueous solution. Moreover, nMOF-253 of 50 nm is successfully applied in fluorescent bioimaging and intracellular Fe(2+) sensing in HeLa cells.

Control of Permanent Porosity in Type 3 Porous Liquids via Solvent Clustering.

ACS Appl Mater Interfaces

January 2025

Geochemistry Department, Sandia National Laboratories, Albuquerque, New Mexico 87123, United States.

Porous liquids (PLs) are an exciting new class of materials for carbon capture due to their high gas adsorption capacity and ease of industrial implementation. They are composed of sorbent particles suspended in a nonadsorbed solvent, forming a liquid with permanent porosity. While PLs have a vast number of potential compositions based on the number of solvents and sorbent materials available, most of the research has been focused on the selection of the sorbent rather than the solvent.

Sulfur functionalized diamondoid phosphines enable building nanocomposites interfacing sp-carbon and gold nanolayers.

Nanoscale

January 2025

Institut de Chimie Moléculaire de l'Université de Bourgogne (ICMUB), UMR CNRS 6302, Université de Bourgogne, 9 avenue Alain Savary, 21078 Dijon, France.

Interfacing metal frameworks with carbon-based materials is attractive for the bottom-up construction of nanocomposite functional materials. The stepwise layering of difunctionalized diamantanes and gold metal from physical and chemical vapor deposition for the preparation of nanocomposites inverts the conventional preparation of metal-organic frameworks (MOFs) and self-assemblies, where the metal is introduced first, and this method delivers metal surfaces with modified properties originating from the sp-carbon core. However, appropriate diamondoid candidates for such an approach are rare.

Carrier-Induced Room-Temperature Half-Metallicity in an Exfoliable Two-Dimensional Cr(TCNB) Metal-Organic Framework.

J Phys Chem Lett

January 2025

Key Laboratory of Precision and Intelligent Chemistry, School of Chemistry and Materials Science, CAS Key Laboratory of Materials for Energy Conversion, CAS Center for Excellence in Nanoscience, University of Science and Technology of China, Hefei, Anhui 230026, P.R. China.

Half-metallicity, enabling 100% spin polarization, is pivotal for spintronics but remains challenging to achieve in low-dimensional materials. Using first-principles calculations, we theoretically propose an experimentally feasible two-dimensional (2D) metal-organic framework (MOF) magnetic semiconductor, Cr(TCNB) (TCNB = 1,2,4,5-tetracyanobenzene). This monolayer can be exfoliated from a Ag(100) substrate due to its low exfoliation energy of 0.

Nanospace Engineering for C Aromatic Isomer Separation.

ACS Nano

January 2025

Department of Chemical and Biomolecular Engineering, National University of Singapore, 117585 Singapore.

C aromatic isomers, namely para-xylene (PX), meta-xylene (MX), ortho-xylene (OX), and ethylbenzene (EB), are essential industrial chemicals with a wide range of applications. The effective separation of these isomers is crucial across various sectors, including petrochemicals, pharmaceuticals, and polymer manufacturing. Traditional separation methods, such as distillation and solvent extraction, are energy-intensive.

Here, a straightforward design is employed to synthesize a nanocatalyst based on a carbon-activated modified metal-organic framework using the solvothermal method. This work presents a simple and practical approach for producing the activated carbon derived from the Thymus plant (ACT) modified with amine-functionalized isoreticular metal-organic framework-3 (IRMOF-3) to create an ACT@IRMOF-3 core-shell structure. Successful functionalization was confirmed through N adsorption isotherms, FT-IR, FE-SEM, TEM, EDS, elemental mapping, TGA, and XRD analysis.
