Ionic metal–organic frameworks (iMOFs): progress and prospects as ionic functional materials

Abstract

The domain of metal-organic frameworks (MOFs) has been the research hotspot to scientific community for last two decades and has witnessed an extraordinary upsurge across various domains in material chemistry....

Porous organic polymers (POPs) for environmental remediation

“…Especially, the past few decades have witnessed the emergence and development of a variety of novel micro-, meso-and even macro-porous materials such as metal-organic frameworks (MOFs), covalent-organic frameworks (COFs), and porous organic polymers (POPs). [10][11][12][13][14][15] Amongst these novel materials, POPs have attracted tremendous scientific attention recently owing to their unique advantage of combining the properties of both polymers and porous materials (Scheme 1). [16][17][18] POPs represent the class of metal free organic materials, constructed from purely organic monomers made of mostly light elements (C, H, O, N, B, etc.)…”

Hydrolytically Stable Luminescent Cationic MOF for Selective Detection of Toxic Organic Arsenic in Water

“…Such phenomena are frequently observed in the case of ionic MOFs. 20,21,55 Moreover, CO 2 gas sorption analysis at 195 K was further performed to validate the porosity of iMOF-12C, which showed a significant amount of gas uptake (Figure S20).…”

“…Toward fabricating a suitable sensory probe, we have chosen a π-electron-rich N-donor linker bearing a conjugated aromatic skeleton, making the MOF highly emissive in nature by virtue of ligand-centered emission. The organic sulfonic acid as a counter-anion gives extra framework functionality as well electronically contributes toward increasing the luminescent property and structural integrity. , Precise selection of d 10 metal ions in synergy with an extended conjugated organic ligand produced a positively charged chemically robust luminous framework furnished with multiple interacting sites for guest analyte molecules. Here, in this report, for the first time, a highly luminescent water-stable cationic iMOF-12C was constructed from an N-donor-based linker Tris­(4-(1 H -imidazol-1-yl)­phenyl)­amine and d 10 metal ion Zn 2+ for precise and sensitive recognition of the organic arsenic molecule roxarsone (ROX) and nitarsone (NIT) from water (Scheme ).…”

Post engineering of a chemically stable MOF for selective and sensitive sensing of nitric oxide

“…29 In this line, linker modulation imparts a great impact in the design of luminescent MOFs which can be easily achieved via post-synthetic modification of the organic ligand or especially the metal cluster of MOFs. 30,31,56…”

“…29 In this line, linker modulation imparts a great impact in the design of luminescent MOFs which can be easily achieved via post-synthetic modification of the organic ligand or especially the metal cluster of MOFs. 30,31,56 The capability to detect low concentrations of nitric oxide is of emerging importance. In order to monitor the water quality and air quality index, it is best to identify harmful NO in water and vapor as early as possible, before the concentrations increase, collect in the local environment, and result in significant harm.…”
