Synthesis of highly refractive and transparent poly(arylene sulfide sulfone) based on 4,6-dichloropyrimidine and 3,6-dichloropyridazine

Facile Synthesis of Monodispersed Polysulfide Spheres for Building Structural Colors with High Color Visibility and Broad Viewing Angle

“…The high refractive index contrast of PSF spheres to their surrounding (i.e., air) can increase the relative reflectivity, thereby increasing the total amount of reflected light, namely, the structural color visibility . Theoretical calculations of the PSF refractive index were carried out based on the molar refractions ( R M ) of atoms or organic groups in the polymer repeating unit according to the Lorentz–Lorenz equation (Equation (S1)) . The calculated results of the refractive index for three PSF spheres with particle sizes of 260, 244, and 211 nm were 1.834, 1.858, and 1.854, respectively.…”

High refractive index materials: A structural property comparison of sulfide‐ and sulfoxide‐containing polyamides

“…Demand for high refractive index (high‐ n ) polymeric materials has been rapidly increased because of their wide range of applications in optical products, such as optical eyewear, optical fibers, windowpanes, lenses, prisms, components for charge‐coupled devices, and as sensor materials in combination with optical waveguides . Their lightweight, dying ability, and impact resistance, and good processability are driving the industry toward the use of polymeric materials rather than inorganic glasses .…”

“…[1][2][3][4] Their lightweight, dying ability, and impact resistance, and good processability are driving the industry toward the use of polymeric materials rather than inorganic glasses. 5 In addition, aromatic polyamides (PAs) as a class of highperformance polymers play important role in modern commercial applications.…”

Synthesis and structure–property relationships of novel thiazole‐containing poly(amide imide)s with high refractive indices and low birefringences

“…High‐refractive‐index (high‐ n ) polymers have been proposed in recent years for their specific potential in advanced optoelectronic applications . Refractive index combined with birefringence (Δ n ), optical dispersion (Abbe number) and optical transparency in the visible region are often involved in the design of high‐ n polymers.…”

“…The introduction of heteroaromatic units containing —C═N—C— or —N—N═C— bonds into polymer backbones can enhance the refractive indices of polymers while maintaining high optical transparency . Over the past two decades, macromolecules containing thiazole, as a heteroaromatic ring containing a sulfur atom and one —C═N—C— moiety, have been reported in the academic literature and have received commercial attention due to their unique optoelectronic applications .…”
