Uranyl-silicotungstate-containing hybrid building units {α-SiW₉} and {γ-SiW₁₀} with excellent catalytic activities in the three-component synthesis of dihydropyrimidin-2(1H)-ones

Abstract

A novel uranyl-containing polytungstate, {K4.2Na18.9H0.9(H2O)20[K4(UO2)3(H2O)6(α-SiW9O34)(γ-SiW10O36)3]}·ca16H2O (U3), was synthesized using Keggin-type precursor [γ-SiW10O36]8- ({γ-SiW10}) and UO2(OAc)2 and was further characterized by single-crystal X-ray diffraction and various techniques. Single crystal X-ray diffraction...

Advancing biomedical applications of polyoxometalate-based metal–organic frameworks: from design to therapeutic potential

“…57 The self-assembly strategy is pivotal in POMOF synthesis, grounded on the principle of molecules or atoms autonomously organising into ordered structures via local interactions. 58 This approach is advan-tageous due to its operational simplicity, yet it exhibits considerable dependence on reaction conditions, including the concentration and type of metal oxide anions, heteroatoms, pH, ionic strength, reducing agents, ligands, and temperature. 59 Achieving full control of the synthesis of POMOF structures continues to be a formidable challenge within POMOF applications.…”

New two fold interpenetrating 3D polyoxovanadate-based metal–organic framework as bifunctional catalyst for the removal of 2-chloroethyl ethyl sulfide and phenolic compounds

“…Polyoxometalates (POMs), a type of inorganic metal oxide cluster with tremendous architectural diversity, exhibit attractive properties [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. As an important branch of the POM family, polyoxovanadates (POVs) have attracted increasing attention because of their diverse structures and remarkable properties.…”

Chiral polyoxometalate–cyclodextrin frameworks via Mn-mediated assembly: Enhanced stability and catalytic activity

“…Polyoxometalate (POM), because of their fascinating structural and chemical versatility, are a recognizable choice in many fields of science, ranging from functional materials and catalysis to magnetism and biomedicine [1][2][3][4][5][6][7]. Metal-organic frameworks (MOFs), which are a class of crystalline porous materials constructed from metal ions and organic bridging ligands, lead to highly uniform porous structures with large surface areas [8][9][10][11][12][13].…”
