Abstract:
The toxic gas H2S has recently emerged as one of the important signaling molecules in biological systems. Thus understanding the production, distribution, and mode of action of H2S in biological system is important, but the fleeting and reactive nature of H2S makes it a daunting task. Herein we report a biocompatible, nitro‐functionalized metal–organic framework as reaction‐based fluorescence turn‐on probe for fast and selective H2S detection. The selective turn‐on performance of MOF remains unaffected even in presence of competing biomolecules.
