Abstract
Tripod-type host molecules have shown new and characteristic cation binding and transport properties especially for Ag+ ion; they have a flexible open-chain skeleton as well as cryptand-like geometry. 1H N.m.r. and binding studies have shown that the Ag+ ion is completely enveloped by the tripod molecule and, in consequence, barely exchanged with K+ and other alkali-metal cations. Such three-dimensional complexation, although similar to that of related double armed crown ethers and cryptands, because of its flexible nature, offers unique and specific transport of Ag+ ion.Keywords
