Abstract Efficient room‐temperature sensors for toxic gases are essential to ensure a safe and healthy life. Conducting frameworks have shown great promise in advancing gas sensing technologies. In this study, two new organic‐inorganic [Cu 2 X (PPh 3 ) ( L )] n , CP1 (X = I) CP2 Br) been synthesized using (pyridin‐4‐yl)‐N‐(4H‐1,2,4‐triazol‐4‐yl)methanimine triphenylphosphine. These exhibit distinct structural arrangements generate 1D coordination polymers (CPs). Due their semiconducting properties, both CPs fabricated into conventional interdigitated electrodes by drop‐casting. Benefitting from the higher electron density of Cu(I) center, demonstrates selective NO with excellent sensitivity reversibility. The material offers one best room temperature chemiresistive performances among MOF/CP‐based materials ultrafast response time (15.5 s @10 ppm). Additionally, convenient synthesis ease device fabrication give advantage. experimental theoretical findings collectively suggest that adsorption on material's surface concomitant effective charge transfer between key its efficacious capabilities.

Published: May 16, 2025

Two-dimensional conjugated metal-organic frameworks (2D c-MOFs) represent a promising class of electrode materials for potassium-ion batteries (PIBs), attributed to their superior conductivity, large specific surface area, high charge carrier mobility, and tunable active sites. However, most reported 2D c-MOF-based cathode PIBs usually encounter challenges, such as low capacity inadequate cycling stability. In this context, we herein designed synthesized new hexahydroxy salicylamide ligand (6OH-HBB) via straightforward two-step synthesis with yield 93%, which was subsequently utilized construct Cu-HBB-MOF multiple sites through an in situ metal coordination-induced planarization strategy. Thanks its abundant the demonstrated outstanding initial 228.1 mA h g-1 at 0.2 A g-1, surpassing porous material-based PIBs. Furthermore, even 5.0 exhibited reversible 103.6 after 2500 cycles, simultaneously maintaining low-capacity loss only 0.011% per cycle achieving Coulombic efficiency up 100%, demonstrating good long-term This work provides fundamental insights into engineering c-MOFs multisite functionality, charting course developing high-performance MOF-based cathodes next-generation energy storage systems.
