Spontaneous Resolution of Racemic Salen-Type Ligand in the Construction of 3D Homochiral Lanthanide Frameworks

“…We focus on the design and synthesis of salen-type lanthanide coordination polymer on the basis of their physical properties, and many interesting structures with unique properties have been obtained. − Among the reported salen-type ligands, N , N ′-bis(salicylidene)-1,2-cyclohexanediamine (H 2 L) is now known as one of the “privileged chiral ligand” derivatives, which is widely used to construct homochiral metal complexes. − It contains four isomers, namely, trans - N , N ′-bis(salicylidene)-(1 S ,2 S )- or (1 R ,2 R )-cyclohexanediamine (H 2 L SS or H 2 L RR ) and cis - N , N ′-bis(salicylidene)-(1 S ,2 R )- or (1 R ,2 S )-cyclohexanediamine (H 2 L SR or H 2 L RS ), which can be a probable candidate to realize the self-assembly of HMOFs from racemate. However, the phenolic hydroxyl groups from H 2 L can serve as a linear spacer to link lanthanide ions, which is suitable to construct three-dimensional (3D) MOFs (see Supporting Information, Scheme S2).…”
