A highly copper selective chromogenic calix[4]arene derivative
In this article, copper selective complexation behavior of 5,11,17,23-tetrakis[( N , N -dicyclohexylamino)methyl]-25,26,27,28-tetrahydroxycalix[4]arene ( 4 ) has been explored. Besides this, the binding ability of 4 toward different metal ions such as Cd 2+ , Co 2+ , Cu 2+ , Hg 2+ , Ni 2+ , Pb 2+ an...

has been investigated by UV-visible and fluorescence spectroscopies. The chromoionophore

shows pronounced selectivity for Cu

even in the presence of other metal ions. The results reveal that Cu

The synthesized ligand

was found to be selective toward Cu

among a series of selected metal ions, which may be due to the compatibility between the metal and ligand. Moreover, ionic radii, nature, number of binding sites, cavity size and geometry of

play an important role in selective complexation. |
