Hydrogen-Bonded Organic Framework Nanosheets with Rich Free Oxygen Atoms for NO₂ Sensing

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 14, 2025

Hydrogen-bonded organic frameworks (HOFs) are under fast development in broad applications but have not been well explored for chemiresistive gas sensing yet primarily due to insufficient active sites. Herein, a new porphyrin-based HOF-199 is constructed by OH···O hydrogen bonds featuring layered networks and rich free oxygen (O) atoms, which further exfoliated into few-layer nonosheets with more dangling O sites through an ultrasound-assisted liquid exfoliation method (namely L-HOF-199). Benefiting from electron-donor sites, L-HOF-199 demonstrates exceptional NO2 properties ambient conditions, achieving remarkable 3.25-fold improvement sensitivity (152% toward 5 ppm of NO2) faster response speed (52 s), relative HOF-199. This work provides promising platform the rational design advanced sensors via functional HOF chemistry.

Metal halide double perovskites with splendid optical features have been considerably investigated for optoelectronic applications. Herein, a series of Mn2+-doped Cs2NaLuCl6 perovskite crystals were prepared. Via adopting the density functional theory calculation, effect Mn2+ doping on electronic structure compound was discussed. It found that crystal can emit intense blue light from host self-trapped exciton (STE) emission. Excited by 320 nm, STE and emissions simultaneously observed in resulting crystals. Owing to efficient energy transfer Mn2+, polychromatic luminescence final products. Moreover, taking advantage various responses emission intensities temperature, thermometric characteristics investigated, their maximum relative sensitivity is 0.99% K-1, which hardly impacted content. Furthermore, prepared exhibit good X-ray radioluminescence properties, low detection limitation 0.99 μGyair s-1.

Published: March 3, 2025

Abstract Dynamic responsive scintillating materials play a significant role in advanced radiation detection technology. However, the issues such as thermal quenching, uncontrollable structure, and unsatisfactory cost, still remain obstacles to diversified development of recent scintillators. Herein, strategy is proposed by assembling well‐designed inorganic organic building units with low cost construct series novel lanthanide MOFs for thermal‐adaptive X‐ray scintillators (TAXS). Based on delicate energy level design, as‐obtained TAXS present ultra‐high relative light yield (max ≈49 700 photons MeV −1 ), tunable luminescence (from green red band), dose rate limit (min ≈118.7 nGy air s ). Importantly, these exhibit unique behaviors including thermal‐facilitated metal‐ligand distance contraction X‐ray‐induced carrier generation, resulting obvious enhanced radio‐luminescence. They maintain perfect linear response (R 2 > 99.8%) excellent stability (>95% after 215 Gy irradiation) during heat treatment. Both TAXS‐based membranes high imaging resolution ≈24 lp mm ) inks customizable printing demonstrate potential work normally at elevated temperatures. Such supports photonic functional fabricate high‐performance harsh condition services.
