摘要

The selective dinitro-substituted derivative of thiacalix [4] arene was synthesized by a three-step route and characterized. Its acid-base properties in a water solution were studied by UV-vis spectroscopy. Its four pKa values were determined by Target Testing Factor Analysis (TTFA).

摘要

The tetranjuo denivative 3 of thiacalix [4] arene was synthesixed and characterixed. Its aciel-hase water solution were studied by UV spectroscopy. The four pKa walues of 3 were determined by target testi analysis (TTFA). The pure UVabsorqton curves and pH distribution curves of five fornes of 3 presented solution were also caculatied by TTFA.

摘要

The acid-base properties of several new calix[4]arene derivatives were studied with chemometric methods by measurement of their UV absorbances under diﬀerent pH. Resolving the acidbase fraction curves with chemometric methods, the pKa of these derivatives were determined and the fraction curves and pure absorbing spectra of each absorbing component in the calixarene system were obtained. The proton dissociation behavior of these derivatives was also discussed in this paper.
