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(...
