Side-chain fullerene polyesters: a new class of high refractive index polymers†
Abstract
By introducing flexible spacers between pendant fullerenes and the backbone, side-chain fullerene polyesters with high fullerene content and good solubility were synthesized by condensation polymerization. These polyesters are a new class of soluble high refractive index polymers (HRIPs) with the highest value of 1.79 at the sodium D line (589 nm).
