摘要

Chiral polymers, with their unique stereochemical features, hold significant importance in biomedical and related fields. Unraveling the structure-property relationship of these polymers is crucial for the rational design and development of functional materials with tailored performances. In this work, a catalyst enantiomer purity regulation strategy was employed to achieve regioselective polymerization of chiral monomers. By regulating the enantiomer purity of chiral (BisSalen)Al catalysts, a series of chiral polymers with varying regioselectivities and G–G linkage contents was successfully synthesized. Performance evaluations revealed that these polymers exhibited thermomechanical properties closely correlated with their microstructures. This study not only provides an effective approach for the controlled synthesis of chiral polymers with tunable regioselectivities but also deepens the understanding of their structure-property relationships, laying a foundation for the development of chiral polymeric materials with on-demand functionalities for diverse applications.
