- •
A ratiometric fluorescence probe for H2S was synthesized using dicyanoisophorone as fluorophore.
- •
The probe showed long emission wavelength (643 nm) and large stokes shift (163 nm).
- •
The probe exhibited high response speed and selectivity toward H2S.
- •
The probe showed high sensitivity toward HS− and the detection limit is as low as 0.13 μM.
