A fluorescent zirconium organic framework displaying rapid and nanomolar level detection of Hg(ii) and nitroantibiotics

Abstract

The solvothermal reaction of ZrCl4 with benzo[1,2-b:4,5-b’]dithiophene-2,6-dicarboxylic acid linker molecule in presence of trifluoro acetic acid modulator afforded the UiO-66 type of metal organic framework (MOF) (IITG-5, IITG = Indian...

A self-cleaning hydrophobic MOF-based composite for highly efficient and recyclable separation of oil from water and emulsions

“…[19][20][21][22][23] The other absorbent materials like core-shell magnetic materials developed by Yu et al have very low surface areas, whereas the MOF materials have very large surface areas, which is advantageous for absorption-related applications. 24,25 Therefore, we synthesized a Zr(IV) based MOF material (1 0 @CF 3 ) with a -OCOCF 3 group by the post-synthetic modification of Zr-BDC-OH MOF (1 0 ) with trifluoroacetic anhydride. The presence of the -CF 3 group is responsible for the development of the hydrophobic nature of 1 0 @CF 3 .…”

Fabrication and DFT Calculation of Amine-Functionalized Metal–Organic Framework as a Turn-On Fluorescence Sensor for Fe3+ and Al3+ Ions

“…For humans and animals, metal ion pollution is not only difficult to degrade but also accumulates in the body. 1,2 Among multifarious metallic elements, iron and aluminum are essential trace elements in diversified physiological processes including oxygen transport, hemoglobin formation, and deoxyribonucleic acid replication. 3,4 Iron and aluminum are widely applied in food packaging, manufacturing cooking utensils, cooking utensils, manufacturing, and other common household items, as well as industrial production, leading to the easy intake of excessive amounts by human beings.…”

A Cd(ii)-organic framework as a highly sensitive and rapid fluorometric sensor for ascorbic acid in aqueous medium

“…26 The use of desired metal ions and various functionalized linkers produces the most suitable LMOFs to detect antibiotics, small organic molecules, toxic gases and important metal ions. 17,26,27 There are few reports on MOF based AA sensing but still there is an opportunity to prepare a better sensor for AA sensing. 3,8,28 In this regard, herein, the presented MOF IITG-6a successfully performs its role to detect AA even in the presence of other potential competitors in water medium.…”
