Self-assembly of indolocarbazole-containing macrocyclic molecules

A successful approach for the synthesis of indolocarbazole-containing macrocycles based upon π-π stacking preorganization of indolocarbazole planes and click-chemistry reactions has been developed. The macrocycles are able to form folded structures with the help of hydrogen-bonding and π-π stacking interactions. Two of the receptors were successfully characterized by single-crystal X-ray diffraction analysis. Our results confirmed that they showed different interesting self-assembly with the anions due to the N-H⋯X- and the triazole C-H⋯X- hydrogen-bonding. © 2010 The Royal Society of Chemistry.link_to_subscribed_fulltex
