Abstract

The FORMATION CONSTANTs (log K), of the complexes formed between a number of amino acids (glycine , L-VALINE and L-ALANINE) with p-sulfonatocalix [4] arene at varying temperatures (25±0.1 to 65 ± 0.1oC) in aqueous solutions and at natural pH of p-sulphonato-calix [4] arene (pH=3.2) by means of UV-Vis spectrophotometeric technique have been investigated. At this pH the guest molecule is in its cationic and zwitterionic forms. The results revealed that the host is quite capable of complexing with the guest in 1:1 guest-to-host ratio. Regarding the FORMATION CONSTANT values, the binding selectivity of the host towards the guests proves in the order (alanine > valine > GLYCINE). The thermodynamic parameters have been assessed and interpreted in matters of the significance of the various interactions responsible for the complexation. A roughly linear relationship between ΔHo and ΔSo has been observed for the studied complexes and it is discussed.
