title: Chiral Amplification by Self-Assembly of Neutral Luminescent Platinum(II) Complexes.
abstract: Two novel enantiomerically pure chiral ligands and the corresponding neutral PtIIcomplexes 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.
