A naphthalimide appended rhodamine based biocompatible fluorescent probe: Chemosensor for selective detection of Hg2+ ion, live cell imaging and DFT study
In this work, we are presenting the design and synthesis of an innovative fluorescentchemosensor: NR-HG, established on a naphthalimide-based rhodamine platform for Hg2+ ion sensing. The probe operates via PET, CHEF, and FRET mechanisms. The fluorescentchemosensor shows an immense selectivity and sensitivity towards Hg2+ ion via the enhancement of ring-opening rhodamine spiro-cyclic structure, with
