摘要
2,6-Bis(benzimidazol-2-yl)pyridine was shown to exhibit potent anionophoric activity via a process of both Cl /NO3 antiport and H+/Cl symport. This is in sharp contrast to the finding that its corresponding N-methylated analog exhibited negligible activity and reveals the importance of the imidazolyl-NH fragments in the anion-transport process.
