Abstract
Center for Integrated Molecular Systems and Department of Chemistry, Division of Molecular and Life Sciences,Pohang University of Science and Technology, Pohang 790-784, KoreaReceived August 4, 2004A novel-type of structurally simple fluorescent chemosensor for oxalic acid was designed, synthesized, andevaluated to show that it detects oxalic acid in methanol with high selectivity over other anions including mono-and dibasic carboxylic acids.Key Words : Chemosensor, Oxalic acid, Photoinduced electron transfer, Cyclen, Isothermal titration calorimetryIntroductionMost of chemosensors are constructed by linkingcovalently a signaling unit to a receptor that recognizes andbinds an analyte molecule.
