However, specific nitrophenols such as para-nitrophenol are recognized as hazardous environmental pollutants. Therefore, their removal or conversion into less harmful compounds, such as 4-aminophenol is of paramount importance. In this study, a copper-based metal-organic framework (Cu-BDC MOF) was synthesized via a simple, cost-effective hydrothermal method at different deposition temperatures. The synthesized materials were characterized using techniques such as X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The Cu-BDC MOF, which exhibited a square plate-like morphology served as an efficient catalyst for the reduction of 4-nitrophenol to 4-aminophenol. Sodium borohydride (NaBH₄) was employed as the reducing agent in conjunction with the Cu-MOF catalyst. An increase in the concentration of NaBH₄ enhanced the catalytic performance by supplying more BH₄- ions, which act as electron donors in the reduction reaction. The 4-NP reduction reaction follows a Langmuir-Hinshelwood mechanism and demonstrates apparent pseudo-first-order kinetics, indicating the reaction proceeds via adsorption of both reactants on the catalyst surface followed by surface-mediated electron transfer.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e70119"},"PeriodicalIF":3.5,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144504283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cover represents the different colors that can be generated by careful choice of the substitutions at the Zn-position in the structure. The metal-to-metal-charge (MMCT) transfer effects along with the allowed d – d transitions were responsible for the observation of vivid colors in the host. The red (Eur3+), green (Tb3+) and blue (Tm3+) emissions using the tellurophosphate host result in white light, which enhances the potential of this material towards solid state lighting applications.

Conventional methods, such as high-temperature distillation, low-temperature crystallization, and electro-deposition are often energy-intensive and costly. Therefore, there is a strong demand for lower-energy, cost-effective strategies to precipitate valuable metals from spent batteries. Here, we employ the anti-solvent method-a low-energy approach-to precipitate precious metals from leachates at room temperature for the separation of dissolved SSEs. Among 61 anti-solvents evaluated, diisopropylamine could achieve a Li precipitation efficiency close to 100%. Additionally, bio-based low-melting mixture solvents (LoMMSs) choline chloride (ChCl):polyethylene glycol 200 (PEG) (1:10) is used as green alternatives to deep eutectic solvents and ionic liquids, offering superior performance in dissolving SSEs from ASSLIBs.

In this study, we first prepared ultrasmall rhodium-molybdenum nanoparticles (Rh-Mo NPs) via a straightforward hydrothermal method, which exhibited remarkable peroxidase (POD)-like catalytic activity. These nanoparticles effectively catalyzed the oxidation of colorless 3,3',5,5'-tetramethylbenzidine (TMB) in the presence of H₂O₂ to generate blue oxidized TMB (ox-TMB), demonstrating superior catalytic performance and substrate specificity. Leveraging this exceptional enzymatic activity, we established a novel colorimetric biosensing platform for sensitive determination of L-cysteine (L-Cys). Experimental data confirmed dual linear absorbance-concentration correlations for L-Cys (0.01-10.0 µM, limit of detection (LOD) = 3.3 nM; 10.0-40.0 µM, LOD = 26.5 nM), exhibiting a segmented dose-response pattern over the 0.01-40.0 µM detection range. The sensing system has three significant advantages: (1) intuitive operation requiring minimal technical expertise, (2) accelerated analysis completion within 5 min, and (3) exceptional sensitivity with low LOD. Notably, the Rh-Mo NPs-based sensing platform could successfully detect endogenous L-Cys in complex biological matrices, including serum and milk samples, confirming their practical applicability in real-sample analysis.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e00613"},"PeriodicalIF":3.5,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144504287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultraviolet-visible absorption spectra and electrochemical behaviors of DBP[12]As confirmed their relatively narrow highest occupied molecular orbital (HOMO)-lowest unoccupied molecular orbital (LUMO) gap values and high HOMO energy levels, which were supported by density functional theory simulations. Parent DBP[12]A adopts a slipped herringbone structure in a crystalline state, with the molecules forming 1D stacks via π-π interactions. The experimentally derived bond lengths, bonding analyses using the Wiberg bond indices, and localized orbital locator calculation support a stronger double bond character for the 12MR bonds than the 4MR bonds in the inner six-membered ring. The chemical shifts of hydrogens in 1H NMR spectra, as well as magnetically induced ring current analyses using quantum chemical calculations, indicate that the 4MRs have stronger antiaromatic character than the 12MR.

The TB-hosts exhibited high decomposition temperatures (353 °C-399 °C) and glass transition temperatures (∼197 °C), demonstrating excellent thermal stability-an essential attribute for vacuum deposition processes and long-term device reliability. Two device architectures, single-host and co-host systems, were investigated to assess their influence on device performance. The co-host approach, using blends with high-triplet-energy electron transport materials (CN-T2T or B3PyMPM), significantly enhanced charge transport, exciton confinement, and operational stability. Notably, the red-emitting co-host device B1 (TB-PhCz:CN-T2T) achieved a 50% increase in external quantum efficiency (EQE) over its single-host counterpart. While green devices based on TB-CzPh and TB-oPhCz exhibited higher peak efficiencies in single-host configurations, co-host devices B2 and B3 demonstrated superior luminance stability and reduced efficiency roll-off. These outcomes highlight the critical role of molecular structure in charge mobility and exciton dynamics.
