Wing‐like molecules… are produced when the basic calixpyrrole skeleton is expanded by the use of bispyrrolylbenzene building blocks. These folded species display shape‐selective anion‐binding properties in solution and in the solid state. The extent of folding depends on the size of the system involved and the nature of the bound anion, with the most elegant “butterfly‐like” behavior being seen in the case of the systems containing three pyrrole and three bispyrrolylbenzene subunits as highlighted by the X‐ray structure included within this cover picture illustration.
