Abstract
E-mail: kangjm@sejong.ac.krReceived May 9, 2011, Accepted May 17, 2011A new anion receptor utilizing carbamate functionality as hydrogen bonding site has been designed andsynthesized. This new receptor 2 has two amide hydrogens and two carbamate hydrogens anchored at 1,8-position of anthracene. These four hydrogens form a concave structure for the anions and the receptor 2 wasfound to be a selective receptor for acetate among the anions investigated.Key Words : Anion receptor, Amide, Carbamate, Hydrogen bonds, AnthraceneIntroductionThere have been considerable efforts to develop efficientartificial receptors for anion recognition and sensing asanions play a major role in biological, medical, environ-mental, and chemical sciences.
