pH-stable Eu- and Tb-organic-frameworks mediated by ionic liquid for aqueous-phase detection of 2,4,6-trinitrophenol (TNP)

Abstract

Two anti-acid-base luminescent metal-organic frameworks (LMOFs), {[Ln2(L)2(OH)(HCOO)]•[H2O]}n (Ln = Eu 1, Tb 2), based on a new π-conjugated organic building block involving both carboxylate and terpyridine group, have been rationally synthesized under the combination of hydro/solvothermal and ionothermal condition (H2L = 4'-(4-(3,5-dicarboxylphenoxy)phenyl)-4,2':6',4''-terpyridine). 1 and 2 are isostructural and feature noninterpenetrated open 3D condensed frameworks constructed by rod-shaped lanthanide-carboxylate building units. The excellent water-stability and pH-stability allow them to be used in an aquatic system. 1 and 2 both show selective and sensitive aqueous phase detection of the well-known nitroaromatic explosive environmental pollutant 2,4,6-trinitrophenol (TNP), which is highly desirable for practical applications. The presence of free pyridine group on LMOFs particles surfaces has been strategically harnessed for serving the purpose of exclusive TNP-sensing.
