摘要: 金属离子对生物体的生命活动起着核心的作用,而一些重金属离子(如Pb2+、Hg2+)在很低浓度时就对生物具有极强的毒性;因此,研究具有金属离子识别特性的智能材料具有重要的理论价值和实用意义。冠醚具有选择性地络合金属离子的能力,研究者们将冠醚的离子识别特性与聚(N-异丙基丙烯酰胺)的相变行为特性相结合制备了一系列离子识别响应型智能材料。综述了近年来基于18-冠-6和15-冠-5两种冠醚分子的离子识别响应型智能材料的研究新进展。目前,基于冠醚的离子识别响应型智能材料仍多处于基础研究阶段,还需要进一步系统深入研究和开发完善。

Abstract: Metal ions play an important role in life activities, but some heavy metal ions (such as Pb2+ and Hg2+) have high toxicity to the organisms even at alow concentration.It is of important theoretical significance and great practical interest to study smart materials with metal ion-recognition properties. Crown ethers have remarkable recognition ability towards specific mental ions.A series of ion-recognition-responsive smart materials composed of crown ethers and responsive poly (N-isopropylacrylamide) (PNIPAM) polymer have been developed.The development of ion-recognition-responsive smart materials based on 18-crown-6 and 15-crown-5 is reviewed.At present, the ion-recognition-responsive smart materials are still at the basic research stage and need further intensive study and development.

Key words: smart materials, ion-recognition, responsive property
