Self-assembly of indolocarbazole-containing macrocyclic molecules

Abstract

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.
