【 摘 要 】

Synthesis of cholic acid-based tripodal receptor (1) and its high chloride ion affinity in comparison with that of chenodeoxycholic acid (2) and lithocholic acid-based receptor (3) was achieved. Anion binding affinities of the receptors were evaluated by 1H NMR and ITC titrations. Tripodal receptor 1 showed a selective affinity for Cl- over Br-, I-, H2PO4-, and CH3CO2-. The selectivity of 1 for Cl- is about 3 times that of Br-, and 17 times that for H2PO4-.
