摘要

Benzimidazolium-based receptors 1-3 were designed and synthesized. On the basis of fluorescence, UV-Vis, and ¹H NMR spectroscopic studies, and X-ray single crystal structure analysis, it was confirmed that the receptor 1 displays strong (C-H) ⁺ X, N-H. X hydrogen bonds and charge-charge interactions with anions. More importantly, these investigations demonstrated that the charged (C-H) ⁺ benzimidazolium and urea moieties play a synergistic role in anion recognition.
