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 catalysis effect of water-soluble calix[4] arene C[4] (calix[4] arene-5,11,17,23-tetrasulfonate) on hydrolysis of ATP in aqueous solution was studied by HPLC. Using laser photolysis and pulse radiolysis, the supramolecular interaction between water-soluble calix [4] arene and ATP was investigated.

摘要

The molecular recognition of tetra (p-t-butyl) tetrathiocalix [4] arene (I) and its three derivatives to heavy metal ions has been investigated by UV spectroscopy and solvent extraction. These erivatives include 5, 11, 17, 23,-tetra-t-butyl-25, 26, 27, 28-tetrakis (acetylmethoxy) tetrathiocalix [4] arene (II), 5, 11, 17,23-tetra-t-butyl-25, 26, 27, 28-tetrakis (2'-hydroxypropyloxy) tetrathiocalix [4] arene (III), 5, 11, 17, 23,-tetra-t-butyl-25, 27-bis (3'-hydroxy propyloxy) tetrathiocalix [4] arene (IV). The UV spectra and solvent extraction of I show that it has an effective molecular recognition to heavy metal ions, especially to Cd2, while IV has a special molecular recognition to Agion. These results confirmed the feasibilities for I to be applied in separation for toxic heavy metal ions Pb2, Cd2 and IV to be used as the sensor compound of Ag ion-selective electrode.

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.
