Hydrogen sulfide (H 2 S) is a crucial endogenous gas transmitter for the evaluation of food spoilage and disease diagnosis. Thus, we have effectively prepared a novel AIE probe EHAT , which displayed a obvious fluorescence color change after the addition of H 2 S (from orangered to green), suggesting that probe EHAT can identify H 2 S with the naked eye. The probe EHAT -based test strip was also developed to conveniently detect H 2 S gas generated during food spoilage. Moreover, the probe EHAT were successfully utilized to image endogenous and exogenous H 2 S in live cells.
