  Disclosed herein are a novel crown ether with bulky and rigid groups and a method for preparing the same. Also provided are a lithium adsorbent comprising the novel crown ether immobilized onto a nanofiber, and a method for preparing the same. The lithium-selective crown ether is synthesized through intermolecular cyclization between a bulky epoxide and a rigid aromatic compound such as 1,2-dihydroxybenzene, and can effectively recover lithium ions. For use as a lithium adsorbent, the novel crown ether with both bulky and rigid subunits is immobilized onto a polymer nanofiber. The crown ether-immobilized polymer nanofibers may be formed into a recyclable membrane.

  本文揭示了一种具有庞大和刚性基团的新型冠醚及其制备方法。还提供了一种锂吸附剂，其中包括将新型冠醚固定在纳米纤维上，并提供了相应的制备方法。锂选择性冠醚是通过庞大环氧化物和刚性芳香化合物（如1,2-二羟基苯）之间的分子间环化合成的，能够有效地回收锂离子。作为锂吸附剂，具有庞大和刚性亚基的新型冠醚被固定在聚合物纳米纤维上。冠醚固定的聚合物纳米纤维可以形成可回收的膜。
