Turn-on luminescence sensing and real-time detection of traces of water in organic solvents by a flexible metal-organic framework

Abstract

The development of efficient sensors for the determination of the water content in organic solvents is highly desirable for a number of chemical industries. Presented herein is a Mg(2+) metal-organic framework (MOF), which exhibits the remarkable capability to rapidly detect traces of water (0.05-5 % v/v) in various organic solvents through an unusual turn-on luminescence sensing mechanism. The extraordinary sensitivity and fast response of this MOF for water, and its reusability make it one of the most powerful water sensors known.

Keywords: crystal engineering; luminescence; metal-organic frameworks; microporous materials; sensors.
