“…The interactions of thiacalix [4]arenes (bearing acetate or amide groups on the lower rim) with transition metals [88] and alkali metal cations [10,12,89] have also been studied. Although the absolute values of the complexation constants for tetraacetates 14a,b,d and 15a,b,d are much lower that those of the corresponding calix [4]arene derivatives, the selectivities for alkali metals were quite interesting.…”

Thiacalixarenes — new members of the calixarene family — are very promising molecules with many potential applications in supramolecular chemistry. The presence of four sulfur atoms in the place of methylene groups imparts many novel features and properties to these molecules. This review deals with the chemistry of thiacalixarenes, and by comparision with “classical” calixarenes, emphasizes their differences in reactivity, unusual conformational preferences and modified complexation abilities.

“…These macrocycles adopt the 1,3-alternate conformation, which seems to be the most favorable for complexation. Tetraethyl p-tert-butylthiacalix [4]arene tetraacetate (3) was synthesized by the procedure described by Lamartine et al [39]. Tetraethyl p-tertbutylcalix [4]arene tetraacetate (4) was obtained from procedure elaborated by Arnaud-Neu [40] and it adopts the cone conformation in solution.…”

The possibility of using capacitance and flat band voltage as measurable quantities for determining amino acids that are neither electroactive nor with strong UV-vis absorption has been explored. The sensors were fabricated by immobilizing calixarene derivatives on Si/SiO 2 /Si 3 N 4 transducers. The measurements were made in sulfuric acid media of ca. pH 1 and in physiological buffer of pH 7.4. The different calixarene derivatives showed varying sensitivities to the amino acids ranging from 8 to 137 mV/decade.

“…It is well known that three-way catalyst (TWC), which was composed of PGM such as platinum (Pt), palladium (Pd) and rhodium (Rh), can reduce more than 99% of emission of autoexhaust [11] . The TC [4]A-CH 2 CONEt 2 shows significant complexation of many cations with maximal level [7] . Sulfur containing calixarenes, which are TC[n]As, are an important class of compounds because they can be used for selective extraction of soft heavy metal ions against alkali, alkaline earth, or other common metal ions [13] .…”

“…Considerable attention has been recently focused on TC[n]As because there are many features that are not presented in chemistry of C[n]As [4] of which bridging sulfide moieties, which may be capable of extensive metal coordination. The complexation ability of the thiacalix [4] arene(TC [4]A) towards neutral molecules or metal ions has also been investigated [5], [6], [7], [8] . However, to our best knowledge, there are few reports on molecular extraction system including organic and inorganic compounds by modified TC [6]A and TC [6] A itself [9], [10], [11] .…”

In this study, a synthesis and extraction capability of two new thiacalix [6]arene (TC[6]A) derivatives modified at the lower or upper rims, which are TC[6]A-CH 2 CONEt 2 (1) and TC[6]A-CH 2 SCOCH 3 (2), respectively, will be discussed. The metal extraction properties of 1, 2, and TC[6]A (3), from automotive catalyst residue solution containing platinum-group metal cations (PGM solution) have been investigated. Compound 3 shows highest extraction capability for Zr cation which is ca. 87% (in pH 4.0 PGM solution). On the other hand, 1 shows the highest extraction capability for Zr cation which is ca. 63% (in pH 3.0 of PGM solution), 2 shows the highest extractability for Pd cation which is ca. 86% (in pH 1.5 of PGM solution) and second highest one for Zr cation which is ca. 57% (in pH 4.0 of PGM solution) respectively.
