Two new Cd-based metal–organic frameworks for afterglow detection of Fe³⁺ and NH₃

Abstract

Luminescent metal-organic frameworks (LMOFs) have been extensively employed as detection probes. However, the majority of the reported probes are fluorescence-based, lacking reports on visible afterglow detection. Herein, we present two...

A Benzothiadiazole-Based Zn(II) Metal–Organic Framework with Visual Turn-On Sensing for Anthrax Biomarker and Theoretical Calculation

“…Compared with “turn-off” responses, the signal change in fluorescence enhancement is easier to detect, and the fluorescence of the probe itself is weak, which can reduce the background signal and improve the sensitivity of the probe. At present, most fluorescence probes in applications belong to the type of enhanced fluorescence probes [ 28 , 29 , 30 ]. The above studies have not only verified the feasibility of planning MOF-based luminescence sensors as biomarkers, but also pointed out the direction for the next steps of research.…”
