Intercalation of chiral molecules into layered metal–organic frameworks: a strategy to synthesize homochiral MOFs

Two homochiral SHG MOFs with remarkable layered architectures were prepared by intercalation of (S or R)-5-oxopyrrolidine-2-carboxylate into layered MOFs assembled from hydrogenated Schiff base L and Zn(II). This is a novel strategy to design and synthesize homochiral coordination polymers and potential nonlinear optical materials.
