Developments of anion-receptors that encapsulate the anions in aqueous solutions

虽然知道高氯酸根离子具有毒性，会抑制新生儿和儿童的生长发育，但由于高氯酸根离子在水中的高度溶解性，去除水中的阴离子相当困难。本工作以双咪唑型配体BITB为原料，合成了一种新型的去除水中阴离子的配位聚合物。此外，利用一种新型的含羟基双咪唑型配体开发了新的分子胶囊体系。该系统通过选择性地将高氯酸盐封装在笼子内来检测水溶液中的高氯酸盐。

Although it is known that perchlorate ion shows toxicity, which inhibits growth of newborns and children, it is quite difficult to remove the anion from water because of the high solubility in water. In this work, new coordination polymers that remove the anion from water were synthesized from bis-imidazole type ligand, bitb. Moreover, new molecular capsule system was developed by using a new bis-imidazole type ligand with hydroxy group. The system detects perchlorate in aqueous solutions by selective encapsulates it within the cage.
