Engineering of Metal–Organic Frameworks as Ratiometric Sensors

Crystal Growth & Design, Journal Year: 2022, Volume and Issue: 22(5), P. 3518 - 3564

Published: April 4, 2022

In the last two decades, metal–organic frameworks (MOFs) have appeared as new multifunctional materials that show a variety of framework architectures depending on choice metal ions and ligands. Among several features been displayed by MOF, one important properties is its luminescent behavior can arise from ligand unit, ions, or cavity guest molecules. Ratiometric fluorescence (RF) sensors be made changing intensity emission peaks associated with multi-emission probes, but synthesis such always challenge, it requires multifluorescence groups having same excitation diverse wavelengths. case MOFs, included modifying unit selecting suitable using desired molecule. As result, MOF act promising candidate for construction ratiometric sensors. Thus, our aim in this review to summarize some recent development has done terms synthesis, mechanism, applications materials.

Recent progress of metal–organic frameworks as sensors in (bio)analytical fields: towards real-world applications

Analytical and Bioanalytical Chemistry, Journal Year: 2023, Volume and Issue: 415(11), P. 2005 - 2023

Published: Jan. 4, 2023

Abstract The deployment of metal–organic frameworks (MOFs) in a plethora analytical and bioanalytical applications is growing research area. Their unique properties such as high but tunable porosity, well-defined channels or pores, ease post-synthetic modification to incorporate additional functional units make them ideal candidates for sensing applications. This possible because the interaction analytes with MOF often results change its structure, eventually leading intrinsic physicochemical which then transduced into measurable signal. porosity allows adsorption very efficiently, while pore sizes/nature and/or installation specific recognition groups allow modulating affinity towards different classes compounds, turn lead good sensor sensitivity selectivity, respectively. Some figures are given illustrate potential MOF-based sensors most relevant application fields, future challenges opportunities their translation from academia (i.e., laboratory testing properties) industry real-world devices) critically discussed.
