Construction of Indium(III)–Organic Framework Based on a Flexible Cyclotriphosphazene-Derived Hexacarboxylate as a Reusable Green Catalyst for the Synthesis of Bioactive Aza-Heterocycles

“…Metal–organic frameworks (MOFs), an emergent and fast-growing class of organic–inorganic hybrid materials with two-dimensional (2D) or three-dimensional (3D) structures assembled by polytopic organic ligands as linkers and metal ions or clusters as nodes through coordination bonding, have garnered significant attention in the last two decades. − Owing to the unique features including structural flexibility, high surface area, high thermal and chemical stability, high crystallinity, facile tailorability, acceptable biodegradability, and biocompatibility, MOFs have been employed extensively in various applications, namely catalysis, − gas adsorption and separation, − drug delivery, , chemical sensing, , magnetism, dye adsorption, and electronic sensors . Benefiting from numerous properties, MOFs can act as heterogeneous catalysts due to several structural features, which are (1) the use of the coordinatively unsaturated metal ions or nodes as acidic/basic sites; (2) the use of polytopic organic ligands as organocatalytic sites; (3) anchors for the encapsulation of extra catalytic centers; (4) postmodification of MOF structures; and (5) controlled decomposition of MOFs into the development of single-site catalysts or nanoparticles. , Because of the necessity for varied compositions and chemical characteristics of MOFs in several catalytic reactions, the deliberate selection of precise metal ions or clusters and multifunctional organic ligands is vital for organic transformation reactions under green environmental reaction conditions.…”

Highly stable Ni8-pyrazolate metal–organic frameworks for adsorption of methylene blue from water

“…However, low adsorption capacity is widely observed in MOFs for the removal of methylene blue from water. 30,[36][37][38][39][40][41] Moreover, most MOFs are susceptible to instability in aqueous environments, leading to framework collapse and consequent impairment of their secondary building units, thereby potentially limiting their application in wastewater treatment. [42][43][44] Therefore, it is envisaged that MOFs with larger pores and enhanced stability will be ideal to overcome these disadvantages by enhancing the adsorption potential of MB and subsequent reusability.…”

Three new Zn(ii) coordination polymers for highly selective and sensitive detection of Fe3+

“…Some factors, such as the organic ligand, metal ion, pH value, reaction temperature, and ratio of ligand to metal, play important roles in the construction of CPs. [26][27][28][29][30][31][32][33] Particularly, organic ligands not only affect the final structure but also influence the properties of CPs. The effective π-system conjugation degree of organic ligands can improve the luminescence behavior.…”
