Record‐High Birefringence Achieved by Linearly Extended π‑Conjugated Building Blocks in Metal‐Free Sulfate

ABSTRACT The advancement of birefringent materials is critical for next‐generation integrated photonics, yet conventional systems face intrinsic limitations in birefringence magnitude. Sulfate crystals offer a promising platform but have been hindered by their dependence on speci...
