Abstract Translation of chirality and asymmetry across structural motifs length scales plays a fundamental role in nature, enabling unique functionalities contexts ranging from biological systems to synthetic materials. Here, we introduce transfer the organic–inorganic interface two-dimensional hybrid perovskites using appropriate chiral organic cations. The preferred molecular configuration spacer cations, R -(+)- or S -(−)-1-(1-naphthyl)ethylammonium their asymmetric hydrogen-bonding interactions with lead bromide-based layers cause symmetry-breaking helical distortions inorganic layers, otherwise absent when employing racemic mixture spacers. First-principles modeling predicts substantial bulk Rashba-Dresselhaus spin-splitting inorganic-derived conduction band opposite spin textures between - -hybrids due broken inversion symmetry strong spin-orbit coupling. ability break one unit another provides design paradigm for emergent properties, including spin-polarization perovskite spintronics related applications.
