Effect of functionalization of metal-organic frameworks on anion sensing

A Multifunctional Tb-MOF Detector for H2O2, Fe3+, Cr2O72–, and TPA Explosive Featuring Coexistence of Binuclear and Tetranuclear Clusters

“…This quenching effect can be expressed by the Stern–Volmer quenching coefficient in the equation I 0 / I = 1+ K sv [M] (where I 0 and I are the luminescence intensity of the Tb-MOF and the suspension of the Tb-MOF mixed with metal ions, respectively, [M] is the molar concentration of metal ions, and K sv is the quenching coefficient of metal ions). 16 − 18 The quenching coefficient K sv for Fe 3+ mixed with the Tb-MOF in H 2 O (0.01 M) is 9580 M –1 .…”

“…Compared with transition metals, lanthanide metal organic frameworks (Ln-MOFs), especially Eu/Tb-MOFs, have been studied widely due to their outstanding luminescence features, including high-purity color, large Stokes shift, high quantum yields, long decay lifetime, and undisturbed emissive energy. Recently, many Eu/Tb-MOFs were applied as an ideal material for identifying small molecules, metal ions, inorganic anions, organic anions, solvents, gases, and explosives. − With the rapid growth of the modern industry, more and more harmful chemical pollutants were released into the environment, including heavy metal ions, volatile organic and toxic gases, etc., which have a serious adverse effect on people’s health and life in the past decades . For example, hydrogen peroxide (H 2 O 2 ) is an essential participant in the energy, food, electrochemistry, enzyme catalysis, and environmental detection as one of the reactive oxygen species (ROS) and is an effective biomarker of several cellular processes, including protein folding, growth, signaling, differentiation, and migration in the cells .…”

Una revisión general de las estructuras metal-orgánicas (MOF) dentro de la química inorgánica

“…En la Figura 5 se muestra una línea de tiempo que muestra el avance que han tenido los MOF a lo largo de la historia y algunas de las aplicaciones más relevantes que se han identificado (Sharmin, 2016;Li, 1999;Eddaoudi, 2002;Rowsell, 2006;Savonnet, 2011;Imaz, 2010;Briones, 2016;Abney, 2017, Hanikel, 2019Rozveh, 2020).…”

Fabrication of a novel heteroepitaxial structure from an MOF-on-MOF architecture as a photocatalyst for highly efficient Cr(vi) reduction

“…[12][13][14][15] In comparison with the prevalent photocatalysts, MOFs have more advantages. [16][17][18] High surface area and desirable topology are their unique properties that facilitate fast transport and the suitable accommodation of targeted molecules. Exclusively, the interval between HOMO and LUMO, which is known as the bandgap, facilitates energy transfer from the linkers to the metal-oxo cluster within some MOFs under light irradiation.…”
