Herein, we report a bio\u2010based aliphatic\u2013aromatic polyimide platform that addresses this challenge through the cooperative molecular design of an isosorbide\u2010derived dianhydride (ISSDA), 4,4\u2032\u2010oxydiphthalic anhydride, cystamine, and a bio\u2010based long\u2010chain aliphatic diamine (DDA). Unlike conventional aromatic polyimides, the nonplanar and nonconjugated ISSDA structure reduces charge\u2010transfer complex formation and prevents compact chain packing, enabling high optical transparency in a self\u2010healable polyimide network. The DDA segment further introduces controlled chain flexibility, lowers the effective healing barrier, and improves segmental mobility required for dynamic disulfide exchange. As a result, the optimized film achieved over 95% transmittance above 650\u00a0nm, thermal healing within 4\u00a0min at 150\u00b0C, and only a 7.8% loss in toughness after healing. DFT\/TD\u2010DFT analyses confirmed that ISSDA suppresses and blueshifts the near\u2010UV electronic transitions relevant to visible transparency, while WAXD analysis revealed enlarged interchain\n                    <jats:italic>d<\/jats:italic>\n                    \u2010spacing and increased amorphous packing.
