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 Cd2+, Co 2+, Cu2+, Hg2+, Ni2+, Pb 2+ and Zn2+ has been investigated by UV-visible and fluorescence spectroscopies. The chromoionophore 4 shows pronounced selectivity for Cu2+ even in the presence of other metal ions. The results reveal that Cu2+ forms 11 host-guest complex with 4. The FT-IR spectroscopic method has also been applied for further confirmation of complex formation between 4 and Cu2+ and found to be satisfactory.
