Metal–organic framework (MOF)-based fluorescence “turn-on” sensors

Abstract

The metal-organic frameworks (MOFs) are the novel category of hybrid porous multifunctional materials with excellent qualitative features. These properties can be fine tune with judicial collection of organic ligand, metal...

Luminescence and Palladium: The Odd Couple

“…This is due to the high added value of these smart materials and the wide variety of applications they show. Just to highlight the most important, we can find luminescent materials in fields with scope as wide as sensors [ 4 ], image biomarkers [ 5 , 6 , 7 , 8 , 9 , 10 ], light-emitting devices (OLEDs) [ 11 , 12 , 13 , 14 ], photodynamic therapy [ 15 ] or theragnosis [ 16 , 17 , 18 , 19 , 20 ], and also in more specific areas such as host–guest encapsulated materials [ 21 ], among others.…”

A de novo strategy for the development of a ZnII–organic framework based luminescent “switch-on” assay for size-exclusive sensitization of the oxidised form of glutathione (GSSG) over the reduced form (GSH): insights into the sensing mechanism through DFT

“…Thus there arise some formidable challenges for the scientific community to design and develop MOFs with predictable physico-chemical properties. In this context, it is noteworthy to mention that there are three forms of fluorescence sensing, including “switch-on”/“turn-on” fluorescence; 19 “switch-off”/“turn-off” 20 fluorescence and “fluorescence shift”. 21 a Amongst them “turn-off” fluorescence is most common and well explored.…”

Colorimetric Response and Real-Field Recognition of Organo-toxins and Antibiotics in Aqueous Medium Using a 2D Coordination Polymer

“…As compared to the variety of luminescent materials, such as organic compounds, conjugated polymers, oligomers, and nanomaterials, fluorescent coordination polymers (CPs) or metal–organic materials (MOFs) have demonstrated distinctive ability for the recognition of numerous analytes. – Interestingly, the CPs or MOFs are a class of inorganic–organic hybrid materials. , Due to the structural versatility of CPs, – they behave as an appropriate sensory material. Additionally, the crystalline nature and the incorporation of proper functionality on the CP network are always beneficial to establish the sensing mechanism.…”
