Synthesis and enantioseparation of chiral Au₁₃ nanoclusters protected by bis-N-heterocyclic carbene ligands.

ABSTRACT: A series of chiral Au₁₃ nanoclusters were synthesized via the direct reduction of achiral dinuclear Au(i) halide complexes ligated by ortho-xylyl-linked bis-N-heterocyclic carbene (NHC) ligands. A broad range of functional groups are tolerated as wingtip substituents, allowing for the synthesis of a variety of functionalized chiral Au₁₃ nanoclusters. Single crystal X-ray crystallography confirmed the molecular formula to be [Au₁₃(bisNHC)₅Cl₂]Cl₃, with a chiral helical arrangement of the five bidentate NHC ligands around the icosahedral Au₁₃ core. This Au₁₃ nanocluster is highly luminescent, with a quantum yield of 23%. The two enantiomers of the Au₁₃ clusters can be separ
