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+) and Zn(2+) has been investigated by UV-visible and fluorescence spectroscopies. The chromoionophore 4 shows pronounced selectivity for Cu(2+) even in the presence of other metal ions. The results reveal that Cu(2+) forms 1 : 1 host-guest complex with 4. The FT-IR spectroscopic method has also been applied for further confirmation of complex formation between 4 and Cu(2+) and found to be satisfactory.
