Abstract

Based on a simple redox reaction, the cerium metal–organic framework (ZJU-136-Ce) exhibits highly sensitive and selective turn-on sensing of AA.

Abstract

We report a cerium metal–organic framework (ZJU-136-Ce) for the turn-on fluorescence sensing of AA. The fluorescence enhancement is attributed to the specific redox reaction between AA and Ce ⁴⁺. The detection limit of AA reaches 7 nM, showing its potential for AA detection in the environmental industry and clinical medicine.

Metal-organic frameworks: functional luminescent and photonic materials for sensing applications.

William P Lustig, Soumya Mukherjee, Nathan Rudd … (2017)

Metal-organic frameworks (MOFs) or porous coordination polymers (PCPs) are open, crystalline supramolecular coordination architectures with porous facets. These chemically tailorable framework materials are the subject of intense and expansive research, and are particularly relevant in the fields of sensory materials and device engineering. As the subfield of MOF-based sensing has developed, many diverse chemical functionalities have been carefully and rationally implanted into the coordination nanospace of MOF materials. MOFs with widely varied fluorometric sensing properties have been developed using the design principles of crystal engineering and structure-property correlations, resulting in a large and rapidly growing body of literature. This work has led to advancements in a number of crucial sensing domains, including biomolecules, environmental toxins, explosives, ionic species, and many others. Furthermore, new classes of MOF sensory materials utilizing advanced signal transduction by devices based on MOF photonic crystals and thin films have been developed. This comprehensive review summarizes the topical developments in the field of luminescent MOF and MOF-based photonic crystals/thin film sensory materials.

Hypersensitive dual-function luminescence switching of a silver-chalcogenolate cluster-based metal–organic framework

Ren-Wu Huang, Yong-Sheng Wei, Xi-Yan Dong … (2017)

The properties of discrete species can sometimes be improved by fixing them into extended materials. This strategy has now been applied to silver(I) chalcogenide/chalcogenolate clusters, resulting in a metal–organic framework with enhanced stability and fluorescent sensing capabilities. Crystallographic analysis allows precise structural determination of guest binding, which is responsible for both emission turn-off and multicoloured turn-on.
