摘要

We report a platform-based approach for designing of aromatic polyesters with customizable optical properties. By employing a series of benzaldehyde-derived cyclic carbonate monomers, we performed ring-opening alternating copolymerization with phthalic anhydride to yield structurally regular polyesters featuring diverse substituents. All monomers underwent smooth copolymerization, producing polymers with controlled molecular weights (Mn=21–45 kDa) and narrow dispersity (Đ=1.04–1.28). Thermal analysis revealed decomposition temperatures above 280 °C and glass transition temperatures exceeding 90 °C, ensuring robust thermal stability. The resulting polyesters showed excellent visible-light transparency, with transmittance greater than 92% between 400–600 nm. Systematic modification of aromatic substituents enabled continuous tuning of refractive indices from 1.563 to 1.622, alongside Abbe numbers ranging from 30.9 to 45.1, highlighting the significant impact of electronic polarizability on optical performance. This work establishes a unified molecular design platform for creating high-performance optical polyesters with predictable and tunable refractive and dispersive properties.
