In situ fabricated MOF–cellulose composite as an advanced ROS deactivator-convertor: fluoroswitchable bi-phasic tweezers for free chlorine detoxification and size-exclusive catalytic insertion of aqueous H₂O₂

Abstract

Combining the merits of structural diversity, and purposeful implantation of task-specific functionalities, metal-organic frameworks (MOFs) instigate targeted reactive oxygen species (ROS) scavenging and concurrent detoxification via self-calibrated emission modulation. Then...

Brønsted Acid-Functionalized Ionic Co(II) Framework: A Tailored Vessel for Electrocatalytic Oxygen Evolution and Size-Exclusive Optical Speciation of Biothiols

“…Building on the immense significance of selectively detecting a particular analyte among several amino acids, a competitive analyte test (CAT) was performed in a mixed environment . For this, 200 μL (1 mM) of individual biothiol was added to the trivially quenched dispersions of MOF@interfering amino acids (Figure b).…”

“…Building on the immense significance of selectively detecting a particular analyte among several amino acids, a competitive analyte test (CAT) was performed in a mixed environment. 9 For this, 200 μL (1 mM) of individual biothiol was added to the trivially quenched dispersions of MOF@interfering amino acids (Figure 5b). Surprisingly, the emission intensity of the mixed suspension drastically dropped only in the presence of biothiols, which attests to 18a as a highly selective sensor even in the concurrent presence of other amino acids (Figure 5b).…”

“…As an alternative, earth-abundant transition metals (Fe, Co, and Ni) have received substantial consideration due to their unique orbital arrangement, , which eases the progress of attachment and detachment of the intermediates during catalysis and decreases the energy barrier for this four-electron transfer reaction . In this context, metal–organic frameworks (MOFs) − have emerged as prolific electrocatalytic materials in CO 2 reduction, the hydrogen evolution reaction (HER), and the OER because of their diversified structures, tailorable pore environment, and presence of task-specific active sites. Further, an ordered assembly of the metal ions/clusters and organic struts not only ensures framework stability during the electrochemical process but also promises rationalizing structure–performance synergies to devise advanced analogues with improved performance over state-of-the-art materials.…”

Highly Luminescent MOF and Its In Situ Fabricated Sustainable Corn Starch Gel Composite as a Fluoro-Switchable Reversible Sensor Triggered by Antibiotics and Oxo-Anions

“…Interestingly, the investigation was continuously focused on synthesizing a MOF composite with a flexible substrate to overcome the obstacle associated with the single MOF matrix for practical application . The corn starch (CS) has acquired significant consideration due to its potential features such as biocompatibility, good flexibility, low commercial value, toxicologically innocuous, and easy availability .…”

Selective and Multicyclic CO2 Adsorption with Visible Light-Driven Photodegradation of Organic Dyes in a Robust Metal–Organic Framework Embracing Heteroatom-Affixed Pores

“…In view of the above-mentioned data, coupled with our continued thrust in developing functionalized porous materials for assorted sustainable applications, − we rationally constructed a novel Zn­(II)-based MOF from the self-assembly of a N-rich linker ( L ) and geometrically bent oba ligand (Scheme ), which exhibits a non-penetrating, three-dimensional (3D) structure with paddle-wheel secondary building units (SBUs). The triangular channels in the MOF are decorated with free nitrogen atoms of the linker and bridgehead oxygen of the carboxylate ligand that leads to a polar pore environment.…”
