Abstract

Abstract: A series of 2,6-bis(phenylethynyl)-4-isobutoxy-pyridine oligomers, including monomer, dimer, and trimer, were prepared and characterized with ¹H and ¹³C NMR spectroscopies and HR-ESI mass spectrometries, respectively. A combination of ¹H-NMR titration experiments, Job's Plot experiments, and HR-ESI mass spectrometries confirmed that the oligomers were able to form triple-stranded helical structures in the presence of silver ions in solution and indicated that the coordination ability of the oligomers were significantly enhanced due to isobutoxy group.

Key words: foldamers, helicates, silver ions, coordination
