I am studying the adsorption of enantiomers on chiral crystals. If someone knows uncommon, but commercially available chiral crystals (or available from your laboratory), please advise me:
-Chiral crystals formed by achiral molecules.
-Chiral crystals formed by molecules with axial, planar or helical chirality (but with the absence of chiral center)
- Сhiral crystals with a porous structure, formed by any molecules
Dear Vladimir, for an initial overview please have a look at the following potentially useful review article which might help you in your analysis:
Introduction to chiral crystallization of achiral organic compounds: Spontaneous generation of chirality
Article Introduction to Chiral Crystallization of Achiral Organic Compounds
Please check if the full text of this article is accessible through your institution. It has unfortunately not been posted as public full text on RG. Good luck with your research!

Cyclodextrins are used in various enantiomer separations (CE/GC/HPLC/NMR). The native CDs, DIMEB, 6-monoamino-βCD, peraminoCDs are crystalline materials and except DIMEB, they are practically insoluble in common organic solvents (apart from DMSO/DMF/HMPT and the like) and oils.
Insoluble (in any common /non-destructive/ solvents) CD-polymers are also suitable and less studied solids.
