Herein, we have strategically designed and developed a new Lewis-acidic 2D Ni-MOF: IITKGP-61 employing mixed ligand synthesis approach.

With the abundant accessible open metal sites (two OMSs per formula unit), the developed framework was explored in the biologically important Hantzsch condensation reaction under the sustainable synthetic pathway. Good-to-excellent yields were achieved for a broad scope of substrates even with lower catalyst loading. Most importantly, to verify the practical utility, MOF: IITKGP-61 was employed for the synthesis of a biologically important 1,4-dihydropyridine molecule with antidiabetic properties in ethanol as green solvent with excellent yield.

This approach integrates sulfur atoms that enhance intersystem crossing (ISC) to the triplet state via spin-orbit coupling, positioning these photosensitizers as suitable candidates for photodynamic therapy applications. In this study, we investigate the photophysical properties and excited-state dynamics of 4-dimethylaminophthalimide (DMAP) and its thionated derivative, thio-4-dimethylaminophthalimide (SDMAP). DMAP exhibits a fluorescence quantum yield of 17%, demonstrating significant fluorescence emissions. In contrast, SDMAP shows negligible fluorescence due to enhanced ISC within 1.0 ± 0.2 ps, which facilitates the rapid triplet state population, with a lifetime of 3.40 ± 0.05 µs under argon-saturated conditions. Notably, the triplet state of SDMAP generates singlet oxygen with a quantum yield of 0.83 ± 0.05, highlighting its high potential for photodynamic therapy. In comparison, DMAP does not produce singlet oxygen and undergoes radiative and nonradiative decay to the ground state within 5 ± 1 ns. These findings underscore the profound impact of thionation, effectively converting DMAP from a relatively fluorescent molecule into a highly efficient photosensitizer for photocatalysis and deep-tissue photodynamic therapy applications.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e71137"},"PeriodicalIF":3.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13532150/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147961646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These complexes exhibit red/near-infrared solid-state phosphorescence (λmax ≈ 730-790 nm) at 77 K, characterized by sub-microsecond lifetimes and significant ligand-to-metal charge-transfer (LMCT) character. Computational analysis reveals that standard density functional theory (DFT) struggles to capture the energetics of this heavy-element emission, establishing these systems as critical benchmarks for validating relativistic quantum-chemical workflows that account for dynamic correlation and spin-orbit coupling. Beyond photophysics, the Pb(II) imides display distinctive nitrene-transfer and oxidative reactivity; reactions with ortho-benzoquinones and tetramethylthiuram disulfide yield sterically crowded azobenzenes, rare catecholate-supported Pb3 clusters, and sulfur-rich dimers.

Yet, the synthesis of COCs remains a challenging affair. In this study, we report a simple sonochemical approach for the gram-scale synthesis of a series of pyridine-substituted COCs. The representative electronic variation via para-and meta-substituted pyridines provided a handle to evaluate the effect of the electronic nature of COCs on the overall redox activity. Furthermore, the electrochemical behavior of COC-XPy and its kinetics were investigated in a homogeneous system to provide insight into their solution-phase electrochemical behavior under neutral aqueous conditions. Cyclic voltammetry (CV) studies revealed a one-electron oxidation pathway at the [Co4O4]4+ core, while pH-dependent studies revealed a proton-coupled electron transfer (PCET) mechanism. Comparison of crude and purified samples by CV revealed that trace Co2+ contaminants disrupt the intrinsic cubane redox chemistry and likely contributed to the oxidative currents reported in earlier studies. Overall, our approach offers a convenient route for the synthesis of COC clusters and may facilitate further studies aimed at understanding their redox behavior and relevance to artificial photosynthetic models.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":"32 33","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/chem.71146","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147961641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The molecular pre-catalyst trans-[Pt(LF)2Cl2] was structurally characterized by single-crystal X-ray diffraction and multinuclear solution-state NMR spectroscopy. Advanced solid-state MAS NMR experiments, including 19F{29Si} REDOR, combined with molecular dynamics simulations, establish well-defined F-Si contacts with internuclear distances on the Å-scale and reveal the organization of the pre-catalyst at the silica interface. A model hydrosilylation reaction demonstrates catalytic activity and retention of the molecular species on the support during turnover.
