Abstract

Herein, a simple fluorescent probe, (E)-1,3,3-trimethyl-2-(4-morpholinostyryl)-3H-indol-1-ium iodide (Mi), based on intramolecular charge transfer (ICT) was synthesized. The probe can rapidly and sensitively sense hydrogen sulphide (H2S) with low detection limit (15 nM). The reaction mechanism was investigated via fluorescence and mass spectra. Moreover, the Mi probe was successfully used for the fluorescent imaging of H2S in living cells, demonstrating its potential applications in biological science. Finally, agar gels based on the Mi probe were fabricated, which could act as a solid optical sensor to conveniently and efficiently detect H2S.
