Hydrogen sulfide (HS) and hydrazine (NH) are toxic compounds in environmental and living systems, and hydrogen sulfide is also an important signaling molecule. However, in the absence of dual-color probes capable of detecting both HS and NH, the ability to monitor the crosstalk of these substances is restricted. Herein, we developed an ESIPT-based dual-response fluorescent probe (BDM-DNP) for HS and NH detection dually responsive sites. The BDM-DNP possessed absorbing strength in the detection of HS and NH, with a large Stokes shift (156 nm for HS and 108 nm for NH), high selectivity and sensitivity, and good biocompatibility. Furthermore, BDM-DNP can be utilized for the detection of hydrogen sulfide and hydrazine in actual soil, and gaseous HS and NH in environmental systems. Notably, BDM-DNP can detect HS and NH in living cells for disease diagnosis and treatment evaluation.
