The dual-directional chemical bridge: decoupling the interfacial roles of spacer cations in two-dimensional/three-dimensional (2D/3D) perovskites
In the bridge model, the inward-facing polar headgroup anchors the metal–halide lattice through coordination and hydrogen bonding, while the exposed terminal segment couples upward through oriented dipoles and pi-contact with the transport layer.
