A reflection on ‘Side-chain fullerene polyesters: a new class of high refractive index polymers’

Abstract

Polymers possessing a high refractive index of over 1.70 are commonly named as high refractive index polymers (HRIPs), and they have garnered enormous attention due to their vital application in organic light-emitting diodes, advanced display devices, antireflective coatings, optical lenses, etc. Our communication in Materials Horizons in 2014 (H. Yan, S. Chen, M. Lu, X. Zhu, Y. Li, D. Wu, Y. Tu and X. Zhu, Mater. Horiz., 2014, 1, 247–250, https://doi.org/10.1039/C3MH00105A) provided a series of side-chain fullerene polyesters with high fullerene contents displaying a quite high refractive index up to 1.79 at 589 nm of the sodium D line. This reflection briefly reviews the impacts and the significance of this work in the field of HRIPs.
