Chiral recognition in aggregation of gold nanoparticles grafted with helicenes.
Chiral recognition was observed in the interactions of gold nanoparticles grafted with (±)-, (M)-, and (P)-helicenethiol. Although the nanoparticles contain equal enantiomeric excess, a 1:1 mixture of (M)- and (P)-nanoparticles aggregated more rapidly in solution than (±)-nanoparticles.
