This study incorporates a series of dianhydrohexitol diastereomers of isosorbide (ISB) and isomannide (IMN) units into the diketopyrrolopyrrole\u2010based backbone as CBSs. It is found that the distorted CBS (IMN) improves the mobility\u2013stretchability properties of the polymer with a highly coplanar backbone, whereas the extended CBS (ISB) enhances those of the polymer with a noncoplanar backbone. Additionally, the different configurations of ISB and IMN sufficiently affect the solid\u2010state packing, aggregation capabilities, crystallographic parameters, and mobility\u2013stretchability properties of the polymer. The IMN\u2010based polymers exhibit the highest mobility of 1.69 cm\n                    <jats:sup>2<\/jats:sup>\n                    V\n                    <jats:sup>\u22121<\/jats:sup>\n                    s\n                    <jats:sup>\u22121<\/jats:sup>\n                    and crystallinity retentions of (85.7, 78.6)% under 20% and 60% strains, outperforming their ISB\u2010based or unmodified counterparts. The improvement is correlated with a robust aggregation capability. Furthermore, the CBS content affects aggregation behavior, notably affecting mobility. This result indicates that incorporating CBSs into the polymer can enhance backbone flexibility via movement and rotation of the CBS without affecting the crystalline regions.\n
