ions observed using this probe is as low as 2.52 × 10−10 M. The observed on-off fluorescence with the periodic addition of Cu2+ ion is explained via an Intramolecular Charge Transfer mechanism (ICT) and the inclusion of 1 in β-cyclodextrin is characterised by 1H-NMR molecular modeling studies. The results show that the present β-CD:1 system, studied in HeLa cells, can be potentially used in monitoring
