High Refractive Index Aromatic and Ether-Containing Polythioureas: Improving Transparency and Mechanical Properties via Reciprocal Hydrogen Bonds

Abstract

Front Cover: In article 2400456, Kenichi Oyaizu and co-workers show that the copolymers consisting of thioureas (red), aromatics (orange), and ethers (blue) display superior mechanical and optical properties than the all-aromatic polythioureas, due to the assistance of the reciprocal hydrogen bonds between thiourea and ether units.
