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.

Block copolymers can self-assemble into nanoscale objects with various morphologies, offering custom nanomaterials for diverse fields of application. However, achieving an amorphous 2D morphology through self-assembly in solution remains challenging. Here, we systematically investigate the structural requirements rod (bottlebrush)-coil (linear) block discs by independently varying side chain and backbone lengths. We identify optimal polymer dimensions that yield well-defined nanodiscs 50-200 nm diameters direct water.

Abstract Polymer nanodiscs, especially with stimuli‐responsive features, represent an unexplored frontier in the nanomaterial landscape. Such 2D nanomaterials are considered highly promising for advanced biomedicine applications. Herein, we designed a rod‐coil copolymer architecture based on amphiphilic, tadpole‐like bottlebrush copolymer, which can directly self‐assemble into core–shell nanodiscs aqueous environment. As side chains made of amorphous, UV‐responsive poly(ethyl glyoxylate) (PEtG) chains, they undergo rapid end‐to‐end self‐immolation upon light irradiation. This triggered nanodisc disassembly be used to boost small molecule release from core, is further aided by morphological change discs spheres.
