Abstract: Objective: To synthesize a novel aromatic diol, 2,4-dihydroxy-N-(naphthalen-8-yl)benzamide, and develop polyesters with improved solubility, thermal stability, and flexibility for high-performance applications. Methods: The diol was prepared via Yamazaki condensation and characterized by FT-IR, ¹H NMR, and ¹³C NMR. Polyesters (PE-16 to PE-20) were synthesized through interfacial polycondensation using TPC, IPC, and their mixtures. Properties were evaluated by viscometry, solubility tests, XRD, TGA, and DSC. Results: The monomer was obtained in 89% yield. Polyesters showed inherent viscosities of 0.42–0.92 dL/g, confirmed ester/amide linkages, good solubility, amorphous nature, Tg of 122–166 °C, and decomposition temperatures up to 404 °C. Conclusion: The synthesized polyesters exhibit balanced solubility, thermal stability, and flexibility, making them suitable for advanced material applications.
