High Refractive Index, Enantiopure Silicones Based on BINOL Journal Articles

abstract

• AbstractThe high refractive index aromatic compound, binaphthol (BINOL), is readily incorporated into silicone polymer chains using the Piers–Rubinsztajn (PR) reaction; alternating and random linear copolymers, and elastomers are available. The highest refractive index (RI) materials are BINOL rich. It is not possible to directly make high refractive index linear polymers with very short HSi‐capped, telechelic silicone chains, as they do not react cleanly. However, chain extending short vinyl‐capped BINOL macromers with simple arylsilanes using hydrosilylation leads to polymers with a molar mass of up to 8000 and refractive indices of up to 1.58. Elastomers are prepared using similar processes. The reactions are facile to practice and suggest BINOL can be harnessed in these and other processes to augment RI.
