A luminescent inorganic–organic hybrid, [Cd(C₁₆H₁₀N₂O₈S)(H₂O)], for the selective and recyclable detection of chromates and dichromates in aqueous solution

Abstract

A three-dimensional inorganic–organic hybrid [Cd(H2L)(H2O)], was shown to exhibit good catalytic activity as well as to detect highly toxic chromate and dichromate anions in aqueous medium with good selectivity.

Turn-off luminescence sensing, white light emission and magnetic studies of two-dimensional lanthanide MOFs

“…[38][39][40][41][42][43] Thus, many harmful ions such as arsenate and chromates, as well as organic molecules including pesticides, explosives, etc., have been detected by the use of turn-off luminescence behaviour. [44][45][46][47][48][49][50][51][52][53] Along this line, we have reported 2D and 3D framework compounds assembled from Ln(III) ions and 2,5-bis( prop-2-yn-1-yloxy)terephthalic acid (2,5-BPTA) that exhibited luminescence and catalytic properties. 54 In these compounds, the coordination spheres of the Ln ions contained H 2 O as a ligand, which is not ideal for luminescence efficiency.…”

Fixing CO2 under Atmospheric Conditions and Dual Functional Heterogeneous Catalysis Employing Cu MOFs: Polymorphism, Single-Crystal-to-Single-Crystal (SCSC) Transformation and Magnetic Studies

“…The versatility of the compounds has been established by their many interesting potential applications in the areas such as sorption, − separation, , luminescence, − catalysis, − proton conduction, − magnetism, , etc. The developments over the years allowed the focus of the research to shift toward preparing the compounds for tailor-made purposes such as high porosity and surface area, increased number of active catalytic centers, multiple chemical functionalities, etc. − To achieve these goals, one needs to make a careful choice of the metal node (ions), a linking ligand that hosts the multiple functionalities, and also a possible secondary ligand. There has been some progress in this direction as well. − …”

Blue-Emitting Ligand-Mediated Assembly of Rare-Earth MOFs toward White-Light Emission, Sensing, Magnetic, and Catalytic Studies

“…Metal–organic frameworks (MOFs), also known as coordination polymers (CPs), have been at the forefront of important hybrid materials during the last two decades. − Their large surface area, tunable porosity, and functionality have contributed toward the target-specific guest-accessible applications in the areas of gas storage and capture, gas separation, catalysis, magnetism, drug delivery, etc. − …”
