Abstract

We synthesized a novel tripodal fluorescent receptor bearing benzimidazole motifs as recognition sites in the pods of the receptor. The recognition behavior of the receptor toward various anions was evaluated in CH ₃CN/H₂O (9:1, v/v) solution. The receptor showed changes in fluorescent intensity only with 1^-, but it showed no significant changes on addition of other anions such as F^-, Cl^-, Br^-, HSO₄^-, NO₃^-, CH ₃COO^-, and H₂PO₄^-.
