Metal–organic framework nanosheets with flower-like structure as probes for H2S detection and in situ singlet-oxygen production

Abstract

Herein, a novel bifunctional flower-like metal–organic framework (MOF) was designed as a probe, which could be activated by H₂S, induce itself disassembly and then release linker, Zn porphyrin. Therefore, the fluorescence of the system is enhanced and ¹O₂ could be produced in situ, opening up a new avenue for selective H₂S detection under physiological pH and controllable ¹O₂ release.
