摘要

Hydrogen sulfide (H2S) is a crucial endogenous gas transmitter for the evaluation of food spoilage and disease diagnosis. Thus, we have effectively prepared a novel Aggregation-Induced Emission (AIE) probe EHAT, which displayed a obvious fluorescence color change after the addition of H2S (from orangered to green), suggesting that probe EHAT can identify H2S with the naked eye and the detection limit was calculated to be 1.5 × 10−7 M for H2S. The probe EHAT-based test strip was also developed to conveniently detect H2S gas generated during food spoilage. Moreover, the probe EHAT were successfully utilized to image endogenous and exogenous H2S in live cells.
