It is challenging but highly desirable to develop a versatile luminescent nanocomposite hydrogel system with tunable structures and properties to expand the potential uses of luminescent materials. Here, multiple amine-functionalized lanthanide-containing hydroxyapatites are synthesized as tailored nanomaterial cross-linkers to interact with polydextran aldehyde through imine bonds. The microstructure, gelation time, luminescence, rheological behavior, mechanical properties, thermal stability, degradation, and swelling capability of the luminescent lanthanide-containing nanocomposite hydrogels are systematically investigated. This study reveals that the strong binding affinity between surface metal ions and capping ligands of the nanomaterial cross-linkers contributes to the densest network and the highest mechanical properties of the nanocomposite hydrogels. In addition, these nanocomposite hydrogels possess dynamic features of self-healing, shear-thinning, and injectability, improving their suitability for advanced applications. The luminescent lanthanide-containing nanocomposite lyophilized hydrogels are also demonstrated in the differentiation of volatile organic compounds. Taken together, the adjustable microstructures and characteristics of this lanthanide-containing nanocomposite hydrogel system highlight its potential for offering guidance in producing diverse luminescent materials with definable performances across various fields.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"47 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These AMO-LDHs were fully characterized and employed as precatalysts for the mild oxidative functionalization of cyclic and gaseous alkanes with aqueous H₂O₂ to give the corresponding alcohols, ketones, and carboxylic acids. Cyclohexane and propane were used as model substrates. The oxidation reactions, occurring under mild conditions (30–50 °C), demonstrated good efficiency with total product yields up to 40% and catalyst turnover numbers up to 370 when using a tetra-heterometallic AMO-LDH precatalyst (AMO-MgCuAlFe). Its enhanced catalytic activity is likely associated with the synergic effect of different metal centers (Cu, Fe, and Al─all having a recognized function in oxidation catalysis).

The reactivity of the complex [Ni(N₃)(L1)] was greater than that of the complex [Ni(N₃)(L2)]. [Ni(N₃)(L1)] gives an N2-triazolato product with an electron-deficient alkyne R₁─C≡C─R₂ with R₁ = R₂ = COOCH₃, COOEt, or R₁ = CF₃, R₂ = COOEt while [Ni(N₃)(L2)] gives a homobimetallic bis(μ-NN’-triazolato) bridged product only with F₃C─C≡C─COOEt. The complex [Ni(N₃)(L2)] reacts with dialkyl acetylene-dicarboxylate alkyne, yielding N1-triazolato products under strictly anhydrous conditions, whereas the same reaction under ambient conditions yielded a new unexpected octahedral complex in which the alkyne is converted into a novel O, O donor bidentate ligand. The nature of the predominant triazolato isomer (N1/N2) was experimentally confirmed by single-crystal X-ray diffraction analysis and also verified by DFT calculations.
