Abstract: This article highlights the recent fundamental study in using achiral and chiral porous materials for the potential applications in asymmetric catalysis. Thanks to the new-generation synchrotron X-ray powder diffraction (SXRD) facilities, we reveal the presence of the unique ‘chiral region’ in achiral zeolites with the MFI topology. Both the inherent site-isolation effect of the active sites and internal confinement restraints in zeolites are critical for creating ‘chiral regions’ that can aid the design of more enantioselective catalytic reactions. We also offer an outlook on the challenges and opportunities of this research area.
