Synthesis of Calix[4] arene Bonded with Coumarin-imino Units and Its Fluorescent Recognition of Metal Ions
Abstract:
A novel fluorescent calix[4] arene derivative(1) bonded with coumarin units as fluorophores and imino groups as ionophores was synthesized by condensation of 5,17-diaminocalix[4] arene with 7-hydroxy-4-methyl-2-oxo-2H-chromene-8-carbaldehyde. The structure of compound 1 was fully characterized by IR,1H NMR,13C NMR and MS. The recognition properties of compound 1 toward transition and heavy metal ions were studied by UV-Vis and fluorescent spectroscopies. The results show that compound 1 can selectively recognize Fe3+ and Cr3+ ions. The complexation ratio of compound 1 with Fe3+or Cr3+ is 1:1. The association constants of compound 1 with Fe3+ and Cr3+ were 4.1 × 105 and 1.07 × 105 L/mol,respectively.
