Heavy‐Halide Coordination and Lattice‐Confined Molecular Alignment Enable Giant Birefringence in Hybrid Metal Halides

ABSTRACT High‐birefringence materials are essential for polarization optics, yet it remains difficult to translate anisotropic molecular building blocks into a strong directionally accumulated crystal‐scale optical anisotropy. Here, we establish a hybrid metal halide engineering...
