Hexabutoxytribenzo[a,g,m]coronenes have been prepared in three steps from readily accessible hexabutoxytriphenylene. Single-crystal X-ray diffraction analysis reveals that these molecules can adopt an extraordinary “double-concave” conformation that makes them ideal hosts for the binding of different guest molecules at each face.
