A phthalimide-based fluorescent probe for H2S with a large Stokes shift has been developed. This probe displayed good selectivity and high sensitivity. Imaging intracellular H2S by using this probe was successfully achieved in living cells.
A new ‘turn-ON’ fluorescent probe, pyrene appended thymine acetamide (PTA), with high sensitivity and selectivity for the detection of uric acid (UA) was developed and first time imaging of uric acid in living cells in water was achieved.
Through rational design, the first TICT based fluorescent H2S probe was developed, which exhibited ideal properties such as fast response, good selectivity, high sensitivity, and it was suitable for visualization of exogenous and endogenous H2S in living cells.
