Aromatic hybrid oligomers that consist of Indolocarbazole, pyridine and substituted benzene were prepared and investigatied their binding affinities with anions. These oligomers are designed to encapsulate an anion by NH and CH hydrogen bonds, thus folding into a helical structure. All the oligomers have an identical hydrogen bonding moiety but differenent π-stacking area between aryl planes. Although the aryl appendages at the end of the oligomers does not directly participate in the binding of anions, they have dramatic effects on the magnitudes of the binding affinities; electron-deficient aryl appendages such as pentafluorophenyl greatly increase the association constants between the oligomers and chloride ions. Details will be described in the presentation.
