Exploitation of Guest Accessible Aliphatic Amine Functionality of a Metal Organic Framework for Selective Detection of 2,4,6-Trinitrophenol (TNP) in Water

Abstract

Highly selective and sensitive aqueous phase-detection of the well-known nitro explosive environmental pollutant 2,4,6-trinitrophenol (TNP) by a water-stable, porous luminescent metal-organic framework has been reported. The presence of a guest accessible aliphatic amine functionality in the MOF channels has been strategically harnessed for serving the purpose of exclusive TNP-sensing in water even in concurrent presence of other nitro aromatic and nitro aliphatic analytes.
