Abstract

The effect of substituents on FRET in two newly designed rhodamine-based Hg²⁺ ion selective chemosensors (L¹ and L²) has been explored by a systematic experimental and theoretical study. Comparison of these sensors in the analytical study and imaging of Hg²⁺ ions in living cells has also been included.
