| Abstract: | A water-soluble pillar[6]arene dodecaamine has been synthesized. 1H NMR and fluorescence studies indicate that pillar[6]arene dodecaamine could selectively and strongly bind acidic amino acids, i.e. glutamic acid and aspartic acid in water. And the complexation behavior of pillar[6]arene dodecaamine towards acidic tripeptide glutathione and short chain length (C3 to C8) dicarboxylic acids in water is also investigated. |
