Being picky: Single‐layered chiral 2D sheet structures with dual chiral void spaces are formed in aqueous methanol solution from discrete clusters of planar aromatic segments with in‐plane up and down AB packing. The slipped cofacial stacks of aromatic segments induce the chirality of the sheet. The nanosheets absorb rapidly one enantiomer from a solution of the racemic mixture with greater than 99 % ee.

Trial separation: 2D layered Pb‐ and Sn‐halide perovskites show surprising optical properties, such as dual excitonic emissions. Such unusual properties are shown to arise through to the interaction between the 2D inorganic layers. Separating the inorganic layers either by molecular intercalation or by increasing the length organic spacer ion reversibly switches the optical properties. Abstract In layered hybrid perovskites, such as (BA)2PbI4 (BA=C4H9NH3), electrons and holes are considered...
