Improving the Cd2+ detection capability of a new anionic rare earth metal–organic framework based on a [RE63-OH)8]10+ secondary building unit: an ion-exchange approach towards more efficient sensors

A new family of microporous anionic rare earth (RE) MOFs based on a hexanuclear (RE)6 secondary building unit along with a post-synthetic ion-exchange method to enhance the metal ion sensing capability of anionic MOFs are reported.

Unravelling the mechanism of water sensing by the Mg2+ dihydroxy-terephthalate MOF (AEMOF-1′)

The amorphous compound [Mg(H2dhtp)(H2O)2] 1′ was shown to be a highly efficient and reusable luminescent sensor for the detection of water in THF, due to its transformation to the strongly emissive complex [Mg(H2dhtp)(H2O)5]·H2O 1.

About this collection

From MSDE

Guest Editors: Professor Stefania Tanase (University of Amsterdam) and Professor Anastasios Tasiopoulos (University of Cyprus)

Hybrid inorganic-organic sensing materials have emerged as a new research field that exploits the interaction between the inorganic and organic components. It allows modulating the materials structure to enhance their selectivity towards a target analyte, and to tune the interplay between structure and properties. These materials can be miniaturized and processed at nanoscale, thereby having the potential for device integration.

This collection of papers features research highlighting the potential of hybrid inorganic-organic materials for sensing applications.
