Selectivity from a rigid sandwich‐type complex : A supramolecular approach was used to prepare chelating ligands that give high selectivity for the linear aldehyde in the rhodium‐catalyzed hydroformylation of 1‐octene. The multicomponent assembly consists of two tris(zinc( II ) porphyrin)phosphite ligands (blue) and three ditopic templates (red) with the rhodium complex (green) in the middle of the structure.
