Abstract

Chemistry Chemistry, Multidisciplinary Physical Sciences Science & Technology
The binding properties of 1,2,3,4-amido derivatives of p-tert-butyl calix[4]arene (4-6) towards various anions (spherical halides, planar trigonal nitrate and tetrahedral hydrogen sulphate) as their tetrabutyl ammonium (TBA) salts have been studied by H-1 NMR technique and using Equi Chem program. The stability constants, log K-ass, varying from 0.76 +/- 0.10 to 2.13 +/- 0.04 have been determined for the mononuclear complexes.
