Özet

A novel (E,E)-dioxime (H2L) containing a 23-membered macrocyclic ionophore was synthesized from the reaction of 2,3-(4'-aminobenzo)-1,4,11,14,17-pentaoxa-6,22-dioxo-7,21-diazacyclotricosane-2-ene (5) prepared from 2,3-(4'-nitrobenzo)-1,4,11,14,17-pentaoxa-6,22-dioxo-7,21-diazacyclotricosane-2-ene (4) and cyanogen di-N-oxide (6). H2L encapsulates and coordinates to alkaline earth metal cations via the oxygen atom to form complexes, H2L.2MX (M = K+, Mg2+, Ca2+ and Ba2+; X = ClO4-). After the complexation with alkaline earth metal cations, H-1-NMR, C-13-NMR and IR data were obtained and a comparison of these spectral data is presented.
