摘要：
Novel calix[4]arenes fixed in the 1,3-alternate conformation and functionalized with thioamide groups have been synthesized and their selectivities for Pb2+ and Cd2+ ions in chemically modified field effect transistors (CHEMFETs)have been evaluated, The 5,27-bis(dimethylaminothiocarbonylmethoxy)-26, 28-dipropoxycalix[4]arene 3 in the 1,3-alternate conformation is more selective for Pb2+ than the analogous cone conformer, The 1,3-alternate calix[4]arene 8 having, in the 25- and 27-positions, two pairs of vicinal thioamide moieties at the same face of the molecule, has the highest selectivities for Cd2+ reported so far.
