摘　　要：用冠醚与类双百草枯合成了新型的4价离子型穴醚,并且初步研究了它与3个客体的络合.4价离子型穴醚与百草枯的络合作用明显.4价离子型穴醚对3个客体有选择性识别作用.分子力学模拟结果也支持了以上结论.A novel tetracationic cryptand combining crown ether and bisparaquat was synthesized. Its complexation with three guests using proton NMR was also reported. The tetracationic cryptand showed selective recognition on three guests. Its theoretical modeling between the cryptand and three guests was reported. The proton NMR experiments were relevant to the theoretical modeling.
