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.
通过使用 L-或 D-BCIP 作为手性诱导剂，分别实现了两种对映异构体金属有机骨架 (MOF) Ce-MDIP1 和 Ce-MDIP2 的手性结晶，其中手性通过固态 CD 光谱进行表征。Ce-MDIPs 对芳香醛的不对称氰硅烷化反应表现出优异的催化活性和高对映选择性；具有 L-PYI 作为手性加合物的同手性 Cd-TBT MOF 对 Aldol 反应表现出立体化学催化作用。
