Crystallization-driven two-dimensional assemblies from a phenothiazine-conjugated poly(l-lactide): redox-responsive tunable emission, white-light harvesting and surface-enabled nanoparticle decoration.

ABSTRACT: Crystallization-driven self-assembly (CDSA) of amphiphilic crystallizable block copolymers represents a powerful tool for constructing precision nanostructures with uniform shapes and dimensions. To date, major efforts have been made towards achieving structural control by employing living-CDSA. Herein, we unravel a new approach for precision two-dimensional (2D) architectures that can exhibit redox-responsive surface-emission color tunability, including white-light harvesting from a single phenothiazine end-capped poly(l-lactide) homopolymer (PTZ-P1) without compromising the intrinsic 2D morphology. By CDSA in 20% isopropanol/water, PTZ-P1 produced lozenge-shaped nanoplatelets with multilayered thickness via crystallization of the poly(l-lactide) core, while the phenothiazine (PTZ)
