This review summarizes the data on the synthesis of coordination compounds containing two or more different metal ions based on fluorinated β-diketonates. Heterometallic systems are of high interest in terms of their potential use in catalysis, medicine and diagnostics, as well as in the development of effective sensor devices and functional materials. Having a rich history in coordination chemistry, fluorinated β-diketones are well-known ligands generating a wide variety of heterometallic complexes. In this context, we focused on both the synthetic approaches to β-dicarbonyl ligands with additional coordination centers and their possible transformations in complexation reactions. The review describes bi- and polynuclear structures in which β-diketones are the key building blocks in the formation of a heterometallic framework, including the examples of both homo- and heteroleptic complexes.

The introduction of two-dimensional (2D) perovskite layers on top of three-dimensional (3D) perovskite films enhances the performance and stability of perovskite solar cells (PSCs). However, the electronic effect of the spacer cation and the quality of the 2D capping layer are critical factors in achieving the required results. In this study, we compared two fluorinated salts: 4-(trifluoromethyl) benzamidine hydrochloride (4TF-BA·HCl) and 4-fluorobenzamidine hydrochloride (4F-BA·HCl) to engineer the 3D/2D perovskite films.

Proteasome inhibitors are effective in treating hematologic cancers but have limited utility in brain tumors due to poor blood-brain barrier (BBB) penetration and metabolic instability. In this study, we developed novel macrocyclic peptide epoxyketone inhibitors with improved drug-like properties. Compounds were screened for cytotoxicity against brain cancer cell lines, permeability (PAMPA-BBB and Caco-2), and metabolic stability.

Polyesters, with their tunable chemical structures and environmental sustainability, have drawn growing attention as solid polymer electrolytes for next-generation solid-state lithium metal batteries (SSLMBs). Through a comprehensive experimental and theoretical study involving the systematic variation of carbon chain lengths in the flexible (diol) and coordinating (diacid) segments, along with selective fluorination at distinct positions along the polymer backbone, 18 types of polyester are fabricated and demonstrate that fluorination at the coordinating segment significantly enhances ionic conductivity by suppressing crystallinity. In contrast, fluorination at the flexible segment reduces ionic migration barriers by providing more homogeneous coordinating sites, thereby improving the lithium-ion transference number, despite increasing chain rigidity and a reduction in overall ionic conductivity.

Fluorine (F)-doped carbon materials (FCMs) were one-pot synthesized and applied as the catalysts for the cycloaddition of carbon dioxide (CO) towards the cyclic carbonate for the first time. In this process, F dopants and oxygen (O)-containing groups on the carbon surface played a key role in enhancing the activity. The FCM synthesized at 500 °C (FCM-500) with 5.

The aluminum electrolysis industry generates massive greenhouse gas emissions dominated by CO and perfluorocarbons (PFCs, CF/CF), presenting dual challenges of climate impact and resource waste. Here, we report a robust nickel-based metal-organic framework (SIFSIX-3-Ni) featuring confined square channels (3.55 Å) that achieves the molecular-sieving separation of CO from CF/CF mixtures.
