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

Herein, a novel bifunctional flower-like metal organic framework (MOF), was designed as probe, which could be activated by H2S, induce MOF depletion and release linker, Zn porphyrinic. So, the fluorescence of the system is enhanced and the 1O2 could in-situ produce, providing a new way to selective H2S detection under physiological pH and control 1O2 release.
