Abstract

Abstract : A novel metal–organic framework (MOF), specifically a Zn-MOF, exhibited excellent performance in highly sensitive and selective sensing of Fe 3+ and hazardous phenol compounds. Abstract : A novel two-fold interpenetrating network, namely, {[Zn(DPTMIA)]·(H2 O)2 (DMF)0.5 } n (HPU-1 ), with rectangular channels was synthesized and structurally characterized.HPU-1 was shown to be potentially applicable as a multi-functional fluorescent probe. It was shown to specifically detect Fe 3+, through a cation exchange mechanism, and hazardous phenol compounds, using a mechanism involving a decrease in the efficiency of the transfer of electrons and energy from the ligands to the metal ions. The detection limits ofHPU-1 for Fe 3+ and the phenol compounds were found to be lower than those of MOFs reported in the literature. ThisHPU-1 probe was shown to be functional in aqueous solution and to be affected neither by the type of solvent nor the pH.
