Abstract

Abstract : A novel lead-based compound is reported as a multi-responsive luminescent sensor for detecting anions, cations and small organic molecules, especially Cr2 O7 2−, CrO4 2−, Fe 3+ and nitrobenzene. Abstract : Two novel lead-based coordination polymers, namely [Pb(cbdcp)]·0.5H2 O·0.5CH3 OH (1 ) and [Pb(cbdcp)] (2 ), have been solvothermally constructed by using a zwitterionic ligand 4-carboxy-1-(3, 4-dicarboxy-benzyl)-pyridinium chloride (abbreviated as H3 cbdcpCl). Compound 1 has a three-dimensional framework displaying a valence-bonded SrAl2 topology with the 4 2 ·6 3 ·8 symbol, while compound 2 has a two-dimensional sheet structure that can be simplified into a three-dimensional π⋯π interaction-connected topology with the {4 4 ·6 2 }2 {4 8 ·6 15 ·8 5 } symbol. Notably, compound 1 proved to be a promising potential luminescent sensor capable of selectively detecting anions, cations and small organic molecules, especially Cr2 O7 2−, CrO4 2−, Fe 3+ and nitrobenzene.
