Key Points

  • The study aims to understand the role of the corona-formed block in morphological transitions of block copolypeptoids.
  • Examined the induced transition from hexagonal platelets to screw-dislocation spirals.
  • Analyzed the effects of steric constraints at the core-corona interface on growth patterns.
  • Utilized liquid crystalline polypeptoids to assess the mechanisms of self-assembly.
  • Identified Ostwald ripening as a key mechanism in mesogenic growth.
  • Documented the formation of periodic screw dislocations and helical ramps in polypeptoid structures.

Abstract

-methyl glycine) (PNMG) block induces a morphological transition from flat platelets to hexagonal spirals with periodic screw dislocations and continuous helical ramps, which is driven by steric constraints at the core-corona interface that introduce packing frustration and redirect mesogenic growth. These findings identify Ostwald ripening as a key mechanism in mesogenic growth and establish the corona-forming block as an active regulator in liquid crystallization-driven self-assembly.
