Chiral environment of catalytic sites in the chiral metal-organic frameworks

Chiral metal-organic frameworks are considered a useful platform in heterogeneous catalysis for enantioselective chemical transformations. However, it has been observed that the enantioselectivity is sensitive to the site at which the reaction takes place, even in a single crystal, since the chiral environment of the catalytic site varies according to its location, e. g., that of the surface is anisotropic, whereas that of the interior is isotropic.
