Here, two new Keggin-type POMOFs [Cd(btbu)2(H2O)2(PMo12O40)] (CUST-636), [Cd(btbu)2(H2O)(SiW12O40)0.5](CUST-638) are synthesized using flexible ligand 1,4-bis(1,2,4-triazol-1-yl)butane (abbreviated as btbu) a by hydrothermal method. PXRD, IR, TG analysis were carried out CUST-636 CUST-638. Then, they prepared into electrode materials (referred to 636-GCE 638-GCE), explore electrocatalytic properties. 638-GCE good performance against KBrO3, KNO2, K2Cr2O7 AA. Furthermore, detection trace Cr(VI) was conducted sensors 638-GCE. The low limits (LODs) CUST-638 0.32 0.45 μM, respectively, lower concentrations in drinking water than maximum allowable concentration specified World Health Organization (WHO).

The latest advances in the study of reactivity metal-oxo clusters toward proteins showcase how fundamental insights obtained so far open new opportunities biotechnology and medicine. In this Perspective, these studies are discussed through lens a family soluble anionic nanoclusters known as polyoxometalates (POMs). POMs act catalysts wide range reactions with several different types biomolecules have promising therapeutic applications due to their antiviral, antibacterial, antitumor activities. However, lack detailed understanding mechanisms behind biochemically relevant reactions-particularly complex biological systems such proteins-still hinders further developments. Hence, special attention is given peptides showcasing molecular-level reaction mechanism. doing so, we aim highlight both existing limitations directions future research on beyond.

Abstract Polyoxometalates (POMs) are multifunctional anionic metal‐oxygen complexes with structural and electronic diversity, as well tunable acid‐base redox properties, resulting in their potential building blocks for constructing temperature‐responsive polyoxometalates‐based materials (TRPMs). TRPMs represent a class of intelligent exhibiting property changes response to temperature fluctuations, offering distinctive applications various fields such catalysis, medicine, sensors, imaging, so on. Though many reported, systematic review including recent advances is still absent. This provides insights into advancements mechanisms, nanostructure design strategies, the characterization TRPMs. Special emphasis placed on enhancing properties by incorporating POMs suitable organic ligands, ionic liquid cations, deep eutectic solvent cationic surfactants, polymers. The incorporation ligands not only enables phase transitions but also enhances other catalyst selectivity drug loading capacity, expanding applications. Consequently, this summarizes delivery release, chemical sensing, discusses future technological challenges. in‐depth understanding may help from nanoscale, guiding inspiring development.
