Based on the chiral helicene‐derived dipyridyl ligands, two pairs of chiral rhomboid metallacycles were constructed conveniently by the coordination‐driven self‐assembly. It was found that the chiral metallacycles showed a supramolecular depiction of the illusory Penrose stairs. Moreover, the enantiomers of the metallacycles not only showed clear mirror imaged circular dichroism (CD) spectra and mirror imaged circularly polarized luminescence (CPL) properties, but also exhibited enhanced chiroptical responses probably due to the PS‐like structures. Narcissistic self‐sorting was further observed in the one‐pot synthesis of these chiral rhomboid metallacycles.
