ABSTRACT
Metal ions are widely distributed in living organisms and environmental systems, therefore, their
monitoring is of great importance. These days, several sophisticated instrumental methods are being
used for the detection of metal ions; however, rapid recognition of metal ions requires powerful tools
namely, colorimetric and fluorescent chemosensors. In this review, Rhodamine B and Rhodamine 6G
based colorimetric and fluorescent chemosensors have been discussed. These methods are simple,
involve low cost, lower detection limit, high selectivity, and sensitivity, thereby used to monitor
real-time metal ions. Several metal ions were detected with high selectivity and sensitivity with the aid
of various derivatives of Rhodamine B and Rhodamine 6G fluorophores conjugated to different ligands.
Besides that, this review is focused on the detection of Cu2+ metal ions in recent years.
