Preparation, structure and luminescent characterization of a series of metal–organic frameworks based on flexible ligands with nitrogen heterocycles and carboxyl

A MOF/DNA luminescent sensing platform for detection of potential COVID-19 biomarkers and drugs

“…Therefore, realtime detection of trace amount of IL-6 and oseltamivir in body fluids with low cost would be highly relevant to mitigate the COVID-19 propagation 1 . Metal-Organic Frameworks (MOFs) are porous crystalline hybrid solids with a wide chemical and structural tunability [4][5] . These materials have been considered so far for a broad range of potential applications from gas storage and separation, heterogeneous catalysis, biomedicine and sensing, including for Covid biomarkers [6][7][8] .…”

“…1 Metal-organic frameworks (MOFs) are porous crystalline hybrid solids with a wide chemical and structural tunability. 4,5 These materials have been considered so far for a broad range of potential applications including gas storage and separation, heterogeneous catalysis, biomedicine and sensing, including for COVID biomarkers. [6][7][8] Among thousands of possible MOF compositions, yttrium based MOFs [9][10][11] possess several attractive features such as high coordination numbers associated with a good chemical and thermal stability while their empty 5d orbitals are of interest from the view of electron transfer processes.…”

Coordination Polymers Based on Highly Emissive Ligands: Synthesis and Functional Properties

“…Both Zn coordination polymers could detect Fe 3+ ions in an aqueous solution via luminescence intensity quenching, which was attributed to the overlap between the absorption band of Fe 3+ and the emission bands of the coordination polymers. [144]. Their emission was attributed to intraligand π-π* transitions, the photophysical characteristics of the coordination polymers are shown in Table 3.…”
