Our synthesis began with octol, which were synthesized by condensation of resorcinol and hydrocinnamaldehyde. Tetrahydroxy cavitand synthesis began with octol, which were synthesized by a four steps. Tetrakis (2-aminomethyl)pyridinyl(carbonylmethoxy) cavitand (cavitand 1) and Tetrakis (3-aminomethyl)pyridinyl(carbonylmethoxy)cavitand (cavitand 2) were prepared from tetrakis［(methoxycarbonyl)methyloxy］cavitand with 2-(aminomethyl)pyridine and 3-(aminomethyl)pyridine. The abilities of synthetic receptors , such as cavitand 1 and cavitand 2, to mediate the transport of cation through a liquid chloroform membrane were determined. The transport rate of metal ion depend on the nature of cation. For the various metal ions, the order of transport rate is Li+ ＞ Na+＞ K+ of cavitand 1 and Ca++ ＞ Mg++＞ K+ ＞ Na+ of cavitand 2. |
