Abstract

Abstract : A multi-responsive luminescent sensor for organic small-molecule pollutants and metal ions based on a metal–organic framework is reported. Abstract : Two silver(i )–lanthanide(iii ) heterometallic-organic frameworks (HMOFs) {[Ln3 Ag3 (BPDC)5 (OX)(H2 O)7 ]·7H2 O} n (Ln = Tb (1 ), Gd (2 )) have been synthesized via a mixed ligand approach using 2, 2′-bipyridine-3, 3′-dicarboxylic acid (H2 BPDC) and oxalic acid (H2 OX) under hydrothermal conditions. Single crystal X-ray diffraction studies showed a (3, 4, 5)-connected new topology of {3·4 2 ·5·6 2 }{3·4 3 ·5 2 ·6 3 ·7}{3·5·6 2 ·9·10}{4 2 ·5·6 3 }{4 2 ·5}{4 2 ·6}{4 3 ·5·6 2 }{4 3 ·6 3 }{4 3 ·6 4 ·8 2 ·10}. Luminescence studies showed that the characteristic emissions of Tb 3+ ions are observed in HMOF1 which can be capable of sensing organic small-molecule pollutants and metal ions. In addition, it can also discriminate the isomers of pentanol as well as quantitatively distinguish benzendiamines which are carcinogenic but used for hair coloring.
