分别以L-和D-BCIP为手性诱导剂，对两种对映体金属有机骨架（MOFs）Ce-MDIP 1和Ce-MDIP 2进行了同手性结晶，并通过固态圆二色性谱对其手性进行了表征. Ce-MDIPs对芳香醛的不对称氰基硅烷化反应具有良好的催化活性和高的对映选择性;以L-PYI为手性加合物的纯手性Cd-TBT MOF对Aldol反应具有立体化学催化作用。
Homochiral crystallizations of two enantiomeric metal-organic frameworks (MOFs) Ce-MDIP1 and Ce-MDIP2 were achieved by using L- or D-BCIP as chiral inductions, respectively, where the chiralities were characterized by solid state CD spectra. Ce-MDIPs exhibit excellent catalytic activity and high enantioselectivity for the asymmetric cyanosilylation of aromatic aldehydes; the homochiral Cd-TBT MOF having L-PYI as a chiral adduct exhibits stereochemical catalysis toward the Aldol reactions.
