The convenient and effective catalytic synthesis of quinazolines holds considerable significance due to their high economic value, designing a cluster-type alkali-resisting catalyst such as polyoxometalates (POMs) still poses significant challenge. Herein, three lanthanum ion-doped steady polyoxophosphitemolybdates with the formulas [CH3NH3]6{La(H2O)3Na[Mo6O12(OH)3(HPO3)4]2}·10H2O (1), [CH3NH3]2{La(H2O)[Mo6O12(OH)3(HPO3)4]}·8H2O (2), [CH3NH3]5{La2(H2O)8Na[Mo6O12(OH)3(HPO3)3 (PO4)]2}·16H2O (3) were synthesized by using HPO32- template. Structural analysis revealed that 1 forms three-dimensional structure through connection La3+ an hourglass-shaped {Na[P4Mo6O27]2} unit. 2 porous channel same {P4Mo6O27} building block. When synthetic microenvironment was adjusted changing type reducing agent, some hypophosphite in units oxidized, thereby altering structure, compound 3 formed. All compounds are alkali-resistant catalytically active toward conversion 2-aminobenzyl alcohol benzonitrile into 2-phenylquinazoline, achieves best yield 91.7%, which is much better than those classic Keggin {PMo12} inorganic CaMoO4, indicating synergistic effect Mo La centers. Also, exhibits good activity reliability catalyzing reactions different substrates.

The rise of multi-drug-resistant (MDR) bacteria poses a severe global threat to public health, necessitating the development innovative therapeutic strategies overcome these challenges. Copper-based nanomaterials have emerged as promising agents due their intrinsic antibacterial properties, cost-effectiveness, and adaptability for multifunctional approaches. These materials exhibit exceptional potential in advanced therapies, including chemodynamic therapy (CDT), photothermal (PTT), photodynamic (PDT). Their unique physicochemical such controlled ion release, reactive oxygen species (ROS) generation, tunable catalytic activity, enable them target MDR effectively while minimizing off-target effects. This paper systematically reviews mechanisms through which Cu-based enhance efficiency emphasizes specific performance field. Key factors influencing properties—such electronic interactions, characteristics, size effects, ligand single-atom doping, geometric configurations—are analyzed depth. By uncovering copper-based nanomaterials, this work aims inspire approaches that improve patient outcomes, reduce burden bacterial infections, health initiatives.
