Naphthyl “capped” triazole-linked calix[4]arene hosts as fluorescent chemosensors towards Fe3+ and Hg2+: an experimental and DFT computational study

Author affiliations

Abstract

Four new naphthyl “capped” 1,2,3-triazole-linked receptors 6a–d have been synthesized and characterized. Their binding properties towards different metal ions have been studied by 1H NMR and fluorescence spectroscopy and the association constants were analysed by a non-linear global fit method. The fluorescent spectral changes show that 6a–d are sensitive and selective towards Fe3+ and Hg2+ ions. DFT calculations of the binding modes of 6a–d with these metal ions are also presented.
