Blending porphyrins and calixpyrroles , the calix[ n ]phyrins 1 ( n =4, 6, 8; x =1, 2, 3; Ar=C 6 H 2 (CH 3 ) 3 ) are easily prepared by condensing an appropriately functionalized dipyrromethane with acetone followed by oxidation with 4,5‐dichloro‐3,6‐dioxo‐1,2‐benzenedinitrile. The structure of these molecules show a competition between planar porphyrinic and cuplike calixarene elements. These molecules bind both anions and cations.
