脲类受体对阴离子的结合、识别和分离

在阴离子受体中,脲基因其作为双氧键给予体,能与许多阴离子结合,成为一类重要的、有效的受体单元,同时该类受体的功能化为阴离子结合行为的检测提供了方便.本文综述了近年来单脲、二脲、多脲及金属辅助的脲类受体的设计合成及对阴离子的结合、识别和分离方面的研究进展.

Anion Binding,Recognition and Separation by Urea-based Receptors

Anion coordination chemistry has attracted much attention because anions play important roles in biology,medicine,catalysis,and environmental science.A large number of anion receptors that employ ureas,amides,indoles,pyrroles and other groups as the binding sites have been reported.Urea can be used as an effective unit to build anion receptors because of its ability of binding anions by donating two parallel hydrogen bonds to oxoanions.Thus the urea-based receptors have been greatly explored in recent years...
