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.
