| Abstract: | The ability of new synthetic receptors, i.e., p-tert-butylthiacalix[4]arenes tetrasubstituted at the lower rim and containing secondary amide groups to form complexes with a number of spherical (F−, Cl−, Br−, I−), Y-shaped (MeCOO−), trigonal (NO3 −), and tetrahedral (H2POO4 −) anions has been studied. It was shown that the nature of substituents on the nitrogen atom of the amide groups and configuration of the macrocycle affect the stability constant values of the forming complexes. |
