Synthesis of the high selective extractant reagents based on the macrocyclic compounds

硫杂杯[n]芳烃由苯环组成，通过硫桥连接，其本身可以与金属阳离子形成主-客体或超分子络合物，因为硫化物基团对金属阳离子具有亲和力。本研究合成了新型硫杂杯[n]芳烃衍生物，对稀有金属具有高选择性萃取能力。结果表明，合成的硫杂杯[n]芳烃衍生物对稀有金属具有高选择性萃取作用。最近，我们成功地合成了一种新的基于硫杂杯[4]芳烃的铂阳离子选择性萃取剂。根据我们的研究成果，我们提交了一些论文，并申请了一些专利，包括美国专利。

Thiacalix[n]arenes are composed of benzene rings, linked via sulfur bridges, which itself can make host-guest or supramolecular complexation with metal cations because sulfide groups has affinity for metal cations. In this Study, we synthesized new thiacalix[n]arene derivatives of high selective extraction ability for rare metals. In the results, some thiacalix[n]arene derivatives were synthesized of high selective extraction for rare metals. Recently, we succeeded the synthesis of new compound of selective extractant ability for platinum cation based on thiacalix[4]arene. We submitted some papers and apply for some patents including U.S. patents based on our results.
