Coumarin-encapsulated MOF luminescence sensor for detection of picric acid in water environment

Here, a luminescence metal-organic frame sensor has been reported that can effectively detect aromatic nitro compounds in water. Based on the mechanism of fluorescence quenching, this sensor can not only efficiently identify picric acid in deionized water environment, but also quantitatively detect picric acid in the range of 0-100 mu M. More importantly, this metal-organic frame sensor is suitable for the detection of picric acid in natural water.

Automated summary

A luminescence metal-organic frame sensor has been developed to detect aromatic nitro compounds in water, specifically identifying and quantitatively detecting picric acid in a range of 0-100 mu M. This sensor is also suitable for detecting picric acid in natural water environments.
