This invention discloses a fluorescent probe that simultaneously distinguishes between hydrogen peroxide and glutathione. The chemical structure of the probe is as follows: This fluorescent probe ingeniously combines a 1,8-naphthalenedimide fluorophore and an isophorone fluorophore, achieving for the first time a dual-channel simultaneous detection of hydrogen peroxide and glutathione.

The invention discloses a double-lock fluorescent probe for detecting H2S and H2O2 and a preparation method and application thereof.The double-lock fluorescent probe for detecting H2S and H2O2 is P1, 1, 8-naphthalimide serves as a fluorescent parent, phenylboronic acid ester and disulfide bond-containing ferrocene are bonded to the 1, 8-naphthalimide fluorescent parent to obtain the double-lock fluorescent probe P1, and the double-lock fluorescent probe P1 is used for detecting H2S and H2O2. Under the dual quenching action of phenylboronic acid ester and ferrocene, the fluorescence of P1 is closed. When only H2S exists, the disulfide bond is cracked, the ferrocene group falls off from the fluorescent matrix, but due to the existence of phenylboronic acid ester, the fluorescence of the probe is still limited. Similarly, when only H2O2 exists, phenylboronic acid ester is oxidized and degraded, but fluorescence of a fluorescent matrix is still very weak due to the PET effect of ferrocene. Only when H2S and H2O2 exist at the same time, P1 starts green fluorescence emission. The probe P1 has a relatively short response time and an excellent recognition effect on H2S and H2O2.
