Synthesis, Complexation and DFT Computational Studies of Bis(naphthyl)methane‐“Capped” Triazole‐Linked Calix[4]arenes as Fe3+ Fluorescent Chemosensors

Abstract

AbstractTwo new substituted‐bis(naphthyl)methane “capped” 1,2,3‐triazole‐linked calix[4]arene receptors have been synthesized and characterized. Their binding properties toward different biologically relevant metal ions were studied by fluorescence spectroscopy titrations and 1H NMR spectroscopy. The fluorescence spectral changes show that are sensitive and selective for Fe3+ ions and the binding modes have been confirmed based upon both the 1H NMR and DFT studies.
