Abstract

Imidazole-based ditopic ligands bearing two chiral alkyl groups (L^RR, L^SS, and L^RS) were synthesized. The ligands formed Pd₂L₄ helicates with palladium ions (Pd²⁺). Self-sorting occurred between L^RR and L^RS to form (Pd²⁺)₂(L^RR)₄ and (Pd²⁺)₂(L^RS)₄ homoligand assemblies, whereas mixing of L^RR and L^SS with Pd²⁺ gave a near statistical mixture.
