Self-assembled nickel(ii)-centered metal–organic square grid complexes for CO₂ sensing

Dalton Transactions, Год журнала: 2025, Номер unknown

Опубликована: Янв. 1, 2025

Detection and monitoring of hazardous CO2 gas are essential for ensuring human health environmental safety, which form part Goal 13 the United Nations Sustainable Development Goals (SDGs). Metal-organic square complexes in thin-film forms explored this work first time as sensors. Two new Ni(II) metal-organic grid [Ni(HL)]4Cl4·26H2O (1) [Ni(HL)]4 (BF4)4·20H2O (2) were achieved by self-assembly, utilizing 1,5-bis(2-benzoylpyridine) thiocarbohydrazone (H2L) building blocks. The formation a molecular [NiHL]44+ unit containing four octahedrally coordinated centers complex 1 was confirmed single crystal X-ray diffraction (SCXRD). Complex 2, conversely, yielded crystals complex, [NiL]4 (2a), from its DMF ethanol mixture. MALDI mass spectral study indicates that metallosupramolecular units stable solution, while thermogravimetric reveals rigidity cationic structures their solid states. solvent accessible pore volume 1952 Å3 (≈18.2%) accordance with TG result 18.1% weight loss up to 272 °C. Hirshfeld surface used void analysis. BET areas 2 observed be 2.390 4.803 m2 g-1, respectively. experimentally solid-state band gap energy ∼1.45 eV, revealing semiconductor characteristics. Thin films both these then developed using drop casting process employed sensing, hosts consist many secondary amine groups. Both demonstrated sensing capability towards gas, found improve further under white light illumination. responses 31% 59% sensors engineered limit detection reliable 500 ppm. thin film sensor working chemiresistive mode outperformed counterpart when operated sensor.

In pursuit of a more effective electro‐sensor for environmentally hazardous nitro phenols detection at the trace level, we have developed two novel complexes [Ag( μ ‐S‐thzt)(Hthzt)(PPh 3 )] 2 ·2CH CH OH ( 1 ) and [Hg (thzt) o ‐phen)]( based on 2‐thiazoline‐2‐thiol (Hthzt). , triphenylphosphine ‐phen were used as co‐ligands, respectively. Both synthesizedcomplexes been characterized by single crystal X‐ray diffraction data,UV–vis., infrared, NMR spectrometry. Geometry around both metal ion is distorted tetrahedral. Noticeably, in complex Hthzt acts bridging well terminal ligand. The intermolecular interaction found further investigated through Hirshfeld surface analysis. On comparing fluorescence intensities Hthzt, order behavior was to be > . electrochemical performance their ability sense 4‐nitrophenol (NP) evaluated modified glassy carbon electrodes detected differential pulse voltammetry (DPV) cyclic (CV) methods. Based responses, shows anelectro‐sensor than With relatively low limit 0.19 μM, great selectivity, acceptable sensitivity, /GCE sensor demonstrated an exceptional linear plot between oxidation peak current NP concentration ranges 0.5–500 μM.
