摘要

Intramolecular noncovalent conformational locks (NoCLs) have emerged as an important strategy for developing high-performance organic/polymeric semiconductors (OPSs) via suppressing the non-radiative decay. Despite extensive investigation into the impact of NoCLs on small molecules, elucidating their influence on the physicochemical properties of conjugated polymers (CPs) remains a critical challenge. By employing a combination of theoretical and experimental methods, it is revealed that the incorporation of NoCLs increases the rigidity of the polymer chain, enhances intermolecular interactions, promotes the formation of pre-aggregates of optimal length, and improves charge transport, providing valuable insights for designing high-performance CPs.
