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 CH3CN/H2O (9:1, v/v) solution. The receptor showed changes in fluorescent intensity only with I-, but it showed no significant changes on addition of other anions such as F-, Cl-, Br-, HSO4-, NO3-, CH3COO-, and H2PO4-.

摘要

我们合成了一种新型三脚架荧光受体，其在受体的支臂中带有苯并咪唑基序作为识别位点。在乙腈/水（9:1，v/v）溶液中评估了该受体对各种阴离子的识别行为。该受体仅对I-表现出荧光强度变化，但在加入其他阴离子如F-、Cl-、Br-、HSO4-、NO3-、CH3COO-和H2PO4-时未表现出显著变化。
