Macrocycles 3 and 5 were prepared according to the literature reports [1, 2]. All reagents and solvents were reagent grade quality and were obtained from commercial suppliers. For synthesis, all solvents were dried and purified as described by Perrin and Armarego [3]. Demineralized water was used in extraction experiments. FTIR spectra were measured on a Perkin Elmer Spectrum 65 spectrometer in KBr pellets. 1H and 13C NMR spectra were recorded on a Varian Mercury 400

MHz spectrometer in CDCl3 and DMSO-d6 (99.9%). Mass spectra were measured on a

Micromass Quatro LC/ULTIMA LC-MS/MS spectrometer. Optical spectra were recorded in the UV-Vis region with a PG-T80+ spectrophotometer in 1 cm path length cuvettes at room temperature. The elemental analyses were obtained with a LECO Elemental Analyzer (CHNS

0932) spectrophotometer. The melting points were determined with an electrothermal apparatus and are reported without correction. In solvent extraction experiment Selecta type shaker with thermostat was used. 11 6,3
