Abstract
A novel conic thiacalix[4]arene derivative (1) with diagonal quinolin-8-yloxy pendants via oxyethylene spacer has been synthesized in one step. The coordination properties of the new ligand towards Ni2 + , Co2 + and Zn2 + ions were studied by UV–vis, fluorescent spectra and 1H NMR titration. The results showed that 1 formed very stable complexes with the three metal ions, and the stoichiometries of 1-Ni2 + , 1-Co2 + and 1-Zn2 + were 1:1, 1:2 and 1:2, respectively.Keywords
