Abstract
A quinolinium-derived anion sensor has been synthesised which shows a turn-off fluorescence response in the presence of anions, with selectivity for acetate. The compound exhibits complex anion binding comprising of a host dimer, 2 : 1 and 1 : 1 host : guest species. Fluorescent quenching is due to both dynamic and static processes with charge transfer being the dominant mechanism.
摘要
一种基于喹啉鎓的阴离子传感器已被合成，该传感器在阴离子存在下表现出关闭型荧光响应，对乙酸根具有选择性。该化合物表现出包含主体二聚体、2:1 和 1:1 主体-客体物种的复杂阴离子结合。荧光猝灭是由动态和静态过程引起的，其中电荷转移是主要机制。
