Two novel enantiomerically pure chiral ligands and the corresponding neutral Pt II complexes have been synthetized and characterized. The self‐assembly properties of the complexes have been investigated using different morphological and photophysical techniques. The two enantiomeric complexes, 4 a and 4 b , show high tendency to self‐assemble into chiral supramolecular aggregates with right ( P ) and left‐handed ( M ) helical configurations, respectively, as proven by SEM and absorption circular dichroism. The formation of such organized structures is driven by the formation of metallophilic and π–π interactions between spatially close Pt complexes with an enhancement of the chiro‐optical properties in the solid state.
