Asymmetric induction in homochiral MOFs: from interweaving double helices to single helices

Abstract

Two three-dimensional (3D) homochiral metal-organic frameworks, integrating double helical chains based on enantiopure ligands and single helical structures braided by 4,4'-bipyridine (bipy) and cadmium clusters, have been synthesized successfully, as a result of complete asymmetric induction between the two types of helix.
