Sulfur‐Free Ultrahigh‐Refractive‐Index Polymers Enabled by Densely Packed Oxygen‐Bridged Dibenzofuran‐Cardo Architectures

ABSTRACT Sulfur‐free polymeric materials simultaneously achieving ultrahigh refractive index ( n > 1.8), low optical dispersion, high visible transparency, and thermal robustness have remained elusive due to the fundamental polarizability–dispersion trade‐off. Here, we introdu...
