Fluorescent Chemosensors as Precision Tools for Bioimaging and Environmental Monitoring: Advances, Challenges, and Future Directions

1,8-Naphthalimide: A Versatile Platform for the Design of Fluorescent Probes Targeting Hydrogen Sulfide in Biological Systems

This review summarizes recent advances in the development of 1,8-naphthalimide-based fluorescent probes for H2S detection and highlights organic reactions that enable selective recognition of H2S, such as reduction, nucleophilic addition, nucleophilic substitution, and intramolecular cyclization.

Recent Advances in Camphor-Derived Small-Molecule Organic Fluorescent Probes.

Camphor, a naturally occurring bicyclic monoterpenoid, has attracted increasing interest as a structural scaffold for the construction of fluorescent probes owing to its rigid framework, facile functionalization, and favorable biocompatibility. In recent years, a variety of camphor-derived fluorescent probes have been...

A "turn-on" Fluorescent Probe with Ions-induced ESIPT for the Detection of Cd2+ and Zn2.

Developing an Aggregation-Induced Emission Enhancement (AIEE) type probe with enhanced emission through metal ion-induced methods has been a significant challenge. In this work, we synthesized an AIEE fluorescent chemosensor P1 via a Schiff base reaction by 8-hydroxyquinoline-2-carbaldehyde and 2,4-difluorophenylhydraz...

A heterocyclic chalcone-based fluorescent chemosensor for selective Cu(II) detection: mechanistic insights and preliminary bacterial imaging applications.

Chalcones are attractive scaffolds for fluorescent sensing applications in environmental and biological matrices. Herein, a heterocyclic arylchalcone-based fluorescent chemosensor (2-TIO) with pronounced intramolecular charge transfer (ICT) character was synthesized and spectroscopically characterized for selective Cu(...
