Integrated Molecular Chirality, Absolute Helicity, and Intrinsic Chiral Topology in Three-Dimensional Open-Framework Materials

While chiral materials are common, few are known that integrate molecular chirality, absolute helicity, and 3-D intrinsically chiral topological nets in one material. Such multihomochiral features may lead to enhanced chiral recognition processes that are important for enantioselective catalysis or separation. Reported here are a series of 3-D open-framework materials with unusual integration of various homochiral and homohelical features, even in the bulk sample.
