Three bis urea based acyclic receptors with fixed spacer and varying size of substituents have been synthesized and their binding behavior with different anions are reported along with the selectivity of these receptors towards anions. The fluorescence quenching of the receptors 2 and 3 on binding with anions is also shown. The receptor 1 binds better with Y-shaped AcO¯ ion whereas receptor 3 binds well with Cl¯ ion.
我们合成了三种具有固定间隔和不同大小取代基的双脲基无环受体,并报告了它们与不同阴离子的结合行为以及这些受体对阴离子的选择性。报告还显示了受体 2 和 3 与阴离子结合时的荧光淬灭。受体 1 与 Y 型 AcO¯ 离子结合得更好,而受体 3 则与 Cl¯ 离子结合得很好。
