The design and development of new phenothiazine-based fluorescent probes, which displays selective fluorescence response to Hg2+ and F− ions in a reversible manner. The probe is the first example that facilitates the detection of Hg2+ at nanomolar concentration.

A phenothiazine based diamino-malenonitrile-linked (P-1) chromogenic and fluorogenic probe was synthesized and characterized for the specific detection of Hg2+ and S2−. The probe P-1 can be used for selective imaging of Hg2+ and S2− in living cells.
