Cascade reaction-based fluorescent probe for detection of H2S with the assistance of CTAB micelles

摘要

We report a turn-on fluorescent probe for H_2 S through a cascade reaction using a new trap group 4-(bromomethyl)benzoate, based on excited-state intramolecular proton transfer(ESIPT) sensing mechanism. The probe showed good selectivity and high sensitivity towards H_2 S and it was capable of detecting and imaging H_2 S in living He La cells, indicating its potential biological applications.
