Research on supramolecular cages formed via noncovalent interactions contributes to the development of receptors that mimic these natural systems. Recently, anion-coordination-driven assembly (ACDA) employing oligourea ligands and trivalent phosphate ions (PO₄ ^3-) has emerged as a promising strategy for constructing responsive supramolecular architectures. These assemblies are stabilized through multiple hydrogen bonds and are capable of undergoing structural transformations in response to external stimuli, offering a conceptual framework for understanding flexibility and environmental adaptability in biological contexts. This mini-review highlights the stimuli-responsive properties of anionic self-assemblies, with a focus on systems involving oligourea ligands and PO₄ ^3- ion. Organized by stimulus type, it discusses multistimuli responsiveness, guest-induced transformations, solvent sensitivity, and light-responsive behaviors.

Furfural is a bio-based valuable compound which can be proficiently upgraded to 4-(2-furyl)-3-buten-2-one (FAc) and 1,4-pentadiene-3-one, 1,5-di-2-furanyl (F₂Ac) via aldol condensation of furfural with acetone. In the present work, efficient Cu-doped MgAl layered double hydroxides (LDH) nanocatalysts are fabricated by coprecipitation and are exploited for furfural conversion to obtained FAc and F₂Ac. The structure-activity relationship is scrutinized by characterizing fresh and spent nanocatalysts via numerous techniques. The good correlation between the amount of weak acidic-weak basic catalytic sites and nanocatalysts performance is established. The superior performance of Cu-0.1 nanocatalyst (Cu-content = 1.85 wt%) in aldol condensation is attributed to the presence of optimum weak acidic sites (0.21 mmol g^-1) and weak basic sites (0.36 mmol g^-1), synergistic acidic-basic effect, nano-sized Cu(OH)₂ nanoparticles (1.6 nm), high BET surface area (181 m²g^-1), and mesoporous architecture of material. Cu-0.1 nanocatalyst delivered 98% FAc selectivity with 100% furfural conversion at 85 °C. Furthermore, at 100 °C, the nanocatalyst gives 55% F₂Ac selectivity with 73% furfural conversion.

The catalytic conversion of CH₄ and CO₂ together into syngas, known as dry reforming of methane (DRM), not only depletes the concentration of these gases but also provides an industrially important synthesis gas. Herein, the active sites (metallic Ni) supported over calcium-stabilized zirconia (Ni-xCaSZ; x = 8, 10, 12, 14 mol%) are investigated toward DRM reaction. Catalysts are characterized by X-ray diffraction, surface area and porosity, X-ray photoelectron spectroscopy, Raman spectroscopy, H₂-temperature-programmed reduction, and thermogravimetry. Calcium stabilizes the cubic phases of ZrO₂ and surges mixed oxide phases like cubic CaZrO₃ and monoclinic CaZr₄O₉. At high mol% of Ca, the interaction between CaO and ZrO₂ is grown, the covalence character about oxygen in MOM' bond is raised, the surface area of catalyst is increased, and coke deposition is restricted. Upon increasing mol% of Ca from 8 to 12 mol%, the moderate-level interaction of NiO over support is established, weak interaction of NiO is declined, and overall concentration of active sites is grown. As a result, 5Ni-12CaSZ achieves the highest 66% CH₄ conversion, 73% CO₂ conversion, and 0.86 H₂/CO ratio at 700 °C reaction temperature. An excess amount of calcium (14 mol%) changes the surface composition of CaZrO_x, as well as it may also block the oxide vacancy, which may inhibit the CO₂ activation vis-à-vis catalytic activity.</p>","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500373"},"PeriodicalIF":2.8,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145111535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A simple electrochemical purification process is employed to remove unwanted copper from the desired products affording up to 88% removal in 10 h. Physicochemical analysis of both purified modified β-CDs (Modβ-CDs) reveales marked differences caused just by the additional methyl group, not only between their physicochemical properties (such as melting point and hydrophilicity) but also in their capabilities to self-assemble forming aggregates at relatively low concentrations, which demonstrates to be efficient structures for encapsulating hydrophobic molecules, as it is demonstrated here with curcumin. These Modβ-CDs spontaneously formes aggregates that presented globular shapes with diameters between 100 and 400 nm (as verified by dynamic light scattering and atomic force microscopy analyses). Such type of aggregates could expand the notion of capturing larger molecules within these Modβ-CD-based structures (by not being confined just to the size of the β-CD toroidal cavity), thus increasing their performances to solubilize in a more efficient way hydrophobic compounds in aqueous solutions.
