Corrected Figure 5: Corrected text in the manuscript (p. 9774, below Figure 5): Owing to the presence of flexible aryl-ether linkages in the polymer repeat unit, which impart a ductile property to the material, PI 1 exhibited the highest elongation with 18.4 ± 5.8%. In cases of the copolyimides PI 5 and PI 6, there was an increase in the tensile strength as compared to the homopolyimides PI 3 and PI 4. This is due to the increased ductility in cases of the copolymers. Furthermore, a high degree of branching often results in brittle polymers with a small degree of mechanical strain due to the lack of chain entanglements. However, the branched polyimides, PI 7 and PI 8, prepared in this study produced stable and free-standing films and showed 3.7 ± 0.6% and 4.6 ± 1.2% elongation at break. This may be attributed to the very high molar masses of the PIs obtained during polymerization. Thus, all of the polyimides showed excellent high tensile strength in the range of 57 ± 7 MPa to 98 ± 17 MPa and high Young’s modulus up to 3.7 ± 0.2 GPa. These exceptional mechanical strength values make these polyimides preferable candidates to be applied commercially. Corrected Table 4: This article has not yet been cited by other publications.

用于高折射率应用的含双（3-（三氟甲基）苯基）噻吩的富硫聚酰亚胺

更正图 5：手稿中的更正文本（第 9774 页，图 5 下方）：由于聚合物重复单元中存在柔性芳基醚键，赋予材料延展性，PI 1 表现出最高的伸长率 18.4 ± 5.8 %。在共聚酰亚胺PI 5和PI 6的情况下，与均聚酰亚胺PI 3和PI 4相比，拉伸强度增加。这是由于在共聚物的情况下延展性增加。此外，由于缺乏链缠结，高度支化通常会导致脆性聚合物具有较小的机械应变。然而，本研究中制备的支化聚酰亚胺 PI 7 和 PI 8 产生了稳定且独立的薄膜，断裂伸长率分别为 3.7 ± 0.6% 和 4.6 ± 1.2%。这可能是由于在聚合过程中获得的 PI 的摩尔质量非常高。因此，所有聚酰亚胺都表现出 57 ± 7 MPa 至 98 ± 17 MPa 范围内的优异高拉伸强度和高达 3.7 ± 0.2 GPa 的高杨氏模量。这些出色的机械强度值使这些聚酰亚胺成为商业应用的优选候选者。更正表 4：本文尚未被其他出版物引用。
