聚合物冠醚保留了小分子冠醚的许多特征,又可回收再用,在一定程度上解决了冠醚化合物的应用问题。但由于聚合物冠醚一般需用小分子冠醚为原料,合成步骤复杂,价格往往比小分子冠醚更加昂贵。近年来,Butler等人提出的从多功能团非冠醚单体直接环化聚合合成聚合物冠醚的途径,是一条有实用价值的合成方法。 Polymer crown ether retains many of the characteristics of small molecule crown ether, but also can be recycled, to a certain extent, solved the application of crown ether compounds. However, due to the fact that polymer crown ether generally needs small-molecule crown ether as a raw material, the synthesis steps are complicated and the price is often more expensive than the small-molecule crown ether. In recent years, Butler et al. Proposed a method of synthesizing polymer crown ether by direct cyclopolymerization of multifunctional non-crown ether monomers, which is a practical synthesis method.
