A novel type of ditopic ion pair receptors based on anionâÏ interaction is reported. Oxacalix[2]arene[2]triazine azacrowns were synthesized efficiently from a one-pot reaction between 2,4-dichloro-4-methoxytriazine and 3,5-dihydroxybenzaldehyde followed by condensation with a diamine and reduction of bisimine; they acted as selective ditopic receptors to recognize ion pairs.
报道了一种基于阴离子–π 相互作用的新型双位点离子对受体。通过将 2,4-二
氯-4-甲氧基三嗪与
3,5-二羟基苯甲醛进行一锅法反应,随后与二胺缩合并还原双
亚胺,高效合成了氧杂卡里克[2]
芳烃[2]三嗪亚冠。它们作为选择性双位点受体,能够识别离子对。
