A Rhodamine B- quinoline conjugate (RSQ) functions as a colorimetric and fluorescence probe for selective recognition of Bi3+ ion based on CHEF assisted FRET process. RSQ visibly changes its colour and fluorescence profile upon addition of Bi3+ ion. The distinctive colour change allows facile discrimination of Bi3+ over other common cations. Lowest concentration of Bi3+ detected by RSQ is 0.05 mu M. RSQ efficiently images intracellular Bi3+ in live SiHa cells.
