摘要：

A new family of bis-ureidic receptors (L-1-L-6) has been synthesised. The binding properties of L-1-L-6 towards different anions (acetate, benzoate, glutarate, malonate, dihydrogen phosphate, hydrogen pyrophosphate, triphosphate, AMP and ADP) have been studied by means of H-1-NMR, UV-Vis and fluorescence spectroscopies and a remarkable affinity for HPpi(3-) has been observed in the case L-3 (in DMSO-d(6) and DMSO-d(6)-5% H2O) which also acts as a fluorimetric chemosensor, even to the naked eye, for this anion. Theoretical calculations helped us explain the binding properties observed.
