Abstract
Combination of calix[4]arenes functionalized at the upper rim at the 5- and 17-positions with amino and formyl groups, respectively, gives a new series of "head-to-head" linked double calix[4]arenes in nearly quantitative yield. The X-ray structure of a modified double calix[4]arene is reported. The novel, highly preorganized receptor molecules complex silver(I) ions (Kass = 9.5 × 105 M-1 in CDCl3); the selectivity of complexation was studied by supported liquid membrane transport experiments and chemically modified field effect transistor measurements.
