Photocontrolled living self-assembly has attracted considerable interest due to its noninvasive, remote control, and real-time features; however, it remained much less explored compared other stimuli-responsive systems. Here, a novel photocontrolled crystallization-driven (P-CDSA) system was constructed by employing an alternating copolymer, poly((hexylthienyl stiff-stilbene)-alt-poly(ethylene glycol)) containing photosensitive stiff-stilbene derivative, as the precursor. The photoinduced trans-to-cis isomerization of derivative segments could occur quickly upon 365 nm light irradiation, leading rapid P-CDSA process producing size-controllable nanoplatelets within 2 min at room temperature. Taking advantage repetitive characteristic copolymers, nanoplatelet morphology independent molecular weight (MW) distribution (Đ) copolymer. areas were precisely controlled adjusting unimer-to-seed mass ratio, following linear relationship. Additionally, lengths major minor axes followed sublinear growth trend, enabling tailored dimensions. area also be programmed sequential on/off switching, showing dependence on irradiation time. This study demonstrates first example two-dimensional CDSA opens new avenue for controlling over 2D architectures.

The utilization of polymer crystallization to manipulate the self-assembly polymeric amphiphiles in solution is gaining increasing attention for design anisotropic core-shell nanoparticles and even more complex hierarchical architectures. Notably, living-crystallization-driven (CDSA) method, which involves seeded growth, has emerged as an ambient temperature approach creating low-dispersity nanomaterials such one-dimensional (1D) cylinders two-dimensional (2D) platelets. This technique offers predictable size control facilitates creation segmented structures with spatially defined compositions functionalities, this process epitaxial regarded intrinsic mechanism living CDSA. For context, Viewpoint, we delineate key aspects CDSA growth a particular emphasis on heteroepitaxial employing crystalline cores distinct chemistries from perspective. Revealing in-depth enables expansion where core functionalities are defined. Utilizing chemically strategies, synthetic processes 2D hollow platelets unique architecture also summarized, special interest soft matter.
