Hydrogen sulfide‐activatable fluorescence turn‐on azide‐containing naphthalimide derivative

Abstract Hydrogen sulfide (H 2 S) acts as a crucial biological and environmental component in a variety of processes. Abnormal levels of H 2 S endogenously generated in human body are associated with various diseases. Meanwhile, H 2 S gas leaked from various manufacturing environments has a fatal effect against the human body. For this reason, H 2 S has been considered as a potential biomarker for the diagnosis and treatment of various human diseases, and as a toxic gas that should be detected when leaked to the workplace for the safety of workers. In this study, we synthesized an azide‐containing naphthalimide derivative that can play as a fluorescence turn‐on probe for H 2 S.
