1.D.61 The Anionophoric 2,6-Bis(Benzimidazol-2-yl)Pyridine (ABBP) Family
2,6-Bis(benzimidazol-2-yl)pyridine exhibits potent anionophoric activity via a process of both Cl-/NO3- antiport and H+/Cl- symport. This is in sharp contrast to the finding with its corresponding N-methylated analog which exhibited negligible activity. These findings revealed the importance of the imidazolyl-NH fragments in the anion-transport process (Peng et al. 2016).
