Article Abstract
Perhaps the most controversial and rare aspect of the halogen bonding interaction is the potential of fluorine in compounds to serve as a halogen bond donor. In this note, we provide clear and convincing examples of hypothetical molecules in which fluorine is strongly halogen bonding in a metastable state. Of particular note is a polycyclic system inspired by Selectfluor, which has been controversially proposed to engage in halogen bonding.

Recent advances in two-dimensional (2D) magnetic materials have promoted significant progress in low-dimensional magnetism and its technological applications. Among them, atomically thin chromium trihalides (CrX with X = Cl, Br, and I) are among the most studied 2D magnets due to their unique magnetic properties. In this work, we employ density functional theory calculations to investigate the mechanical and electronic properties of CrX monolayers in the presence of in-plane uniaxial strain.

In this study, we introduce a set of novel computational strategies based on second-order Mo̷ller-Plesset perturbation theory (MP2), enhanced through acceleration techniques, such as the resolution of the identity (RI). These approaches are further refined via spin-component scaling (SCS), following Grimme's methodology, and are specifically calibrated for the quantitatively accurate prediction of weak interaction energiesinteractions that play a critical role in biological systems. Among the developed methods, three variants exhibit outstanding performance, surpassing the accuracy of several state-of-the-art, nondynamical electronic structure techniques.

The persistent threat of pathogenic microorganisms demands the development of innovative scaffolds with dual antibacterial and antifungal activities. Herein, we report the synthesis and characterization of a novel series of benzothiazole-thiazole hybrids (4a-4f) a three-step route, confirmed by NMR and MS analyses. The compounds were screened against Gram-positive, Gram-negative, mycobacterial, and fungal strains using disk diffusion and REMA assays.

BN-fused aromatic compounds have garnered significant attention due to their unique electronic structures and exceptional photophysical properties, positioning them as highly promising candidates for applications in organic optoelectronics. However, the regioselective synthesis of BN isomers remains a formidable challenge, primarily stemming from the difficulty in precisely controlling reaction sites, limiting structural diversity and property tunability. Herein, we propose a regioselective synthetic strategy that employs 2,1-BN-naphthalene derivatives, wherein selective activation of N-H and C-H bonds is achieved in conjunction with -halogenated phenylboronic acids.
