- Abstract
The performance of ordinary calixarene can be improved with introducing of sulfur, nitrogen atom. Treatment of thiacalix[4]arene hydrazides derivative 3 with aryl aldehyde derivatives 4, the novel thacalix[4] crowns derivatives 5 containing amides and schif-base units were syntheszzed in high yields with the weak acid catalyst. The new compounds were characterized by elemental analyses, ESI-MS, ¹H NMR spectra. At the same time, we studied the coordination properties of novel thiacalix [4]arene derivatives 5 and series of alpha amino acids. The results showed that the thiacalixarene crown have an effective coordination ability and selectivity on amino acids.
