Efficient Proton Conduction through [N···X···N]⁺ Halogen Bond Coordination in Halogen‐Bonded Organic Frameworks

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Фев. 9, 2025

Abstract Advancing anhydrous proton‐conducting materials is essential for the fabrication of high‐temperature (>373 K) polymer electrolyte membrane fuel cells (HT‐PEMFCs) and remains a significant challenge. Herein, halogen‐bonded organic frameworks linked by [N···I··N] + interactions are reported as outstanding conductive materials. By incorporating carbazole groups into monomers, two highly crystalline ( XOF‐CSP/CTP ) constructed. These XOFs exhibit high intrinsic conductivity (σ = 1.22 × 10 −3 S cm −1 under conditions. Doping with H 3 PO 4 allows nitrogen sites I on pore walls to stabilize tightly confine network within porous framework through hydrogen bonding, thereby enhancing proton conditions 1.02 −2 ). Temperature‐dependent curves theoretical calculations indicate that transport governed low‐energy barrier hopping mechanism. excellent stability maintain across broad temperature range. This work provides new platform designing potential exchange membranes.

Enhanced Synergistic Photothermal–Chemotherapy in Bacterial Keratitis Treatment Using Halogen‐Bonded Organic Frameworks (XOFs) Based on N⋯Br⁺⋯N Bonds

Aggregate, Год журнала: 2025, Номер unknown

Опубликована: Апрель 29, 2025

ABSTRACT The swift progression of bacterial keratitis necessitates expeditious therapeutic intervention. Present methodologies are characterized by their protracted duration and invasiveness, which often result in suboptimal antibiotic therapy. Consequently, there is an imperative requirement for the development novel approaches management keratitis. In this study, we present two types XOFs connected [N···Br + ···N] interactions. These frameworks were using 1 H NMR, IR, XPS, SAXS, HR‐TEM. Two‐dimensional (2D) structural models established based on PXRD data theoretical simulations. application these as antibacterial agents treatment explored, effects different connection knots hydrophilicity efficacy compared. As expected, effect interactions superior to [N···I TPPA ‐based with good better than TPPE XOFs. addition, a photothermal agent (IR820) was loaded onto XOF(Br)‐TPPA combined chemotherapy, experimental results indicating substantial enhancement efficacy. This work not only deepens our understanding halogen‐bonded organic but also paves way biomedical materials.

An Imidazole‐Based Halogen‐Bonded Organic Framework for the High‐Sensitive Detection of Nitrofuran Antibiotics

Chinese Journal of Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Апрель 25, 2025

Comprehensive Summary Nitrofuran antibiotics threaten human health and the environment due to their toxicity persistence. Their detection is challenging low concentrations interference, while fluorescence sensing offers superior sensitivity selectivity for effective monitoring. In this work, a novel halogen‐bonded organic framework, XOF‐TPEM , was introduced, constructed using an imidazole‐based ligand AIE molecule, TPEM . The framework successfully characterized by various techniques, including 1 H NMR, PXRD, XPS, FT‐IR, HRTEM, SAED, SEM EDS, confirming its excellent crystalline structure. As electron‐donating fluorophore, fluorescent demonstrates potential as selective sensor electron‐deficient nitrofuran antibiotics. Experimental results show that it exhibits high detecting nitrofurans such NFT, FZD, FLD, NFZ, with LODs of 9.7 ppb, 11.0 19.7 236.1 respectively. Mechanistic studies indicate outstanding performance attributed inner‐filter effect occurring between Through comparison pyridine‐based XOF, superiority imidazole ligands in constructing XOFs demonstrated. This study presents luminescent highlights frameworks, underscoring significant expanding functional applications.
