Abstract

Applying magnetic substrates, magnetized perpendicular to the surface, we were able to crystallize from racemic solution pure conglomerates of several molecules. The resolution is based on the spin-dependent charge reorganization (SDCR) effect. By having two surfaces with opposite magnetization, it was possible to simultaneously crystallize on each surface a different enantiomer. The method does not require any seeding or chemical modification and is generally employable to any conglomerate. A system is presented for performing the separation, while the racemic mixture flows between the two magnetic surfaces.
