A pyrene-based probe bearing benzothiazole ionophore (Py-BTZ) was synthesised as a “turn-on” fluorescent chemosensor for the detection of Fe3+ and Fe2+ ions in CH3CN : H2O (1 : 1, v/v) solvent mixes.
A barbituric acid–triphenylamine adduct displayed interesting aggregation-induced emission enhancement (AIEE) features in a THF–water co-solvent system and can act as a fluorescence turn-on probe for Hg2+.
Glutathione stabilized carbon dots show good dispersion, high fluorescence and aggregation-induced emission enhancement properties which could be used as a “turn-on” chemosensor for detecting temperature and Fe3+ in aqueous solution and cells.
A turn-on fluorescence method has been designed for the determination of cellular GSH levels based on the controlled aggregation-induced emission enhancement of self-assembled CuNCs.
