Resorcinarene podand with amine-functionalized side arms - Synthesis, structure, and binding properties of a neutral anion receptor

Article abstract of DOI:10.1002/ejoc.200900814

The synthesis and structure of a neutral resorcinarene host: bearing four amine-functionalized side arms is described. The anion binding properties were investigated in solution by ¹H NMR spectroscopic titration and diffusion experiments and in the gas phase by mass spectrometrlc studies. It was observed that in solution 1:2 (host/guest) complexes were formed between the resorcinarene host: and the basic fluoride and acetate anions, whereas in the gas phase 1:1 complexes with other anions (Cl^-, HCOO^-, NO₃^-, and BF₄^-) were detected additionally.
