Polyimides (PIs), recognized for their exceptional thermal stability, are extensively employed in advanced applications, including aerospace, flexible displays, solar cells, flame-retardant materials, and high-temperature filtration materials. However, with the continuous advancements science technology, demand improved performance of PIs these application areas has increased significantly. In this study, four spirobis(indene)-bis(benzoxazole) diamine monomers (5a, 5aa, 5b 5bb) were designed synthesized. These copolymerized pyromellitic dianhydride (PMDA) 4,4-diaminodiphenylmethane (ODA) to develop Kapton-type PIs. By varying copolymerization molar ratios different diamines, a series novel ultrahigh-temperature-resistant PI films successfully prepared, it was found that incorporating highly rigid twisted structure into matrix enhances rigidity polymer chains restricts mobility, thereby significantly improving films. When 5a ODA at 1:9 4:6, glass transition temperature (Tg) from 396 °C 467 >520 °C, respectively. also exhibit mechanical properties, modulus increasing 1.6 GPa 4.7 GPa, while demonstrating low dielectric performance, as evidenced by decrease constant (Dk) 3.51 3.08 under 10 GHz high-frequency electric field. Additionally, molecular dynamics simulations further explore relationships between structure, condensed states, film providing theoretical guidance development polymers ultrahigh resistance superior overall performance.
