A color turn-on fluorescent probe for real-time detection of hydrogen sulfide and identification of food spoilage

A color and fluorescence turn-on H2S probe is synthesized, achieving real-time detection of H2S in pure water solution with high selectivity. Importantly, the probe is able to sense H2S gas in air via the probe-deposited test paper, which has been successfully used for food spoilage identification.
