A novel luminescent Pb(II) - organic framework exhibiting rapid and selective detection of trace amount of NACs and Fe3+ with excellent recyclability

Abstract

A novel three-dimensional metal organic framework Pb3O2L (1) (H2L =4-(1H-tetrazol-5-yl)phenol) with an unique 3D network structure, exhibiting excellent luminescence and good stability in water and other organic solvent. 1 can act as a promising dual functional sensor for detecting and recognizing nitroaromatic explosives (NACs) and Fe3+ ions through fluorescence quenching with high selectivity and sensitivity in aqueous phase. Importantly, 1 as the fluorescent sensor of Fe3+ can be simply and quickly regenerated, which represented a rare example in the reported luminescent sensor of Fe3+ ions. Furthermore, the potential in application can be further increased by the naked eyes detection and the preparation of luminescent test plates. Experimental and theoretical calculations indicate the luminescence quenching is attributed to an electron and resonance energy transfer between MOF and analytes. The present work contributes to the development of MOF materials research, specifically in the application as biological and environmental fluorescent sensor.
