Route i: Enantiopure molecules are obtained through chiral resolution, form enantiopure crystals and one-handed crystal aggregates. Route ii: Racemic compounds form a pair of enantiomorphs through a self-sorting process, which then aggregate into chiral crystal aggregates with opposite sense, separately. Manual selection is needed to obtain optically active structures. Route iii: In this work, the hierarchical chiral structures are directly generated from racemic solutions in a single process.
