Special Issue Information

Dear Colleagues,

To date, chemical sensors have been applied in many fields, and their rapid development has provided great convenience for human activities. This Special Issue aims to report on the latest research progress in the field of chemical sensors in the Dalian University of Technology, from theoretical research to practical application in various fields. The main topics include, but are not limited to, the following research directions: small-molecule organic fluorescent sensors and their application in research into biological detection; metal complex phosphorescent sensors and their application in detecting small-molecule pollutants; and the development and application of wearable electrochemical sensors and versatile sensors. All topics include review articles and research articles.

Nitroaromatic-explosives (NEs) not only threaten global security but are also recognized as a highly toxic pollutant. Metal–organic framework Zn-Ms (Zn-M1, Zn-M2) were synthesized in this study via the coordination-driven self-assembly of Zn ions and a carbazole-based ligand L containing an aldehyde group. They inherited the excellent fluorescence performance of ligand L and could work as a fluorescent sensor for detecting picric acid (PA) at low concentrations. Zn-Ms showed an emission at 450 nm and exhibited a higher fluorescence quenching efficiency toward PA than other related NEs. The results suggest that the fluorescent response might be attributed to the inner filter effect (IFE); Förster resonance energy transfer (FRET); and possibly, photo-induced electron transfer (PET). In addition, the critical role of the aldehyde group as a recognition site was corroborated using a post-modification strategy. Full article
