摘要

•Enantioseparation of 4,4’-bipyridines containing chalcogen and π-hole sites.•Chalcogen and π-hole bond can drive enantioseparations in HPLC environment.•Mechanistic aspects of σ- and π-hole bond-driven enantioseparations are discussed.•The Source Function tool has been extended to the electrostatic potential.
