Metal–organic framework nanosheets with flower-like structure as probes for H2S detection andin situsinglet-oxygen production

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.
