Self-Assembly of Polymer Nanostructures through Halogen Bonding Interactions of an Iodoperfluoroarene-Functionalized Polystyrene Derivative
Bibliographic record
Abstract
A structurally novel iodoperfluoroarene-substituted polystyrene has been synthesized, and its noncovalent halogen bonding interactions with polymeric Lewis bases have been studied. RAFT polymerization was used to generate halogen bond donating polystyrene derivatives with low dispersities. Coassembly of the halogen bond donor polymer with an amine-functionalized methacrylate block copolymer was achieved using a solvent switching protocol and studied by electron microscopy and dynamic light scattering analysis. The structures obtained include spheres, wormlike structures, and vesicles as well as “inverted” morphologies such as hexagonally packed hoops and bicontinuous structures, which have been challenging to access by conventional assembly methods. The ability to access such inverted structures suggests that complexes generated by noncovalent interactions between complementary macromolecules can display high effective packing parameters, giving rise to behavior that has generally required unconventional macromolecular architectures (e.g., dendrimers, branched, or triblock copolymers). The effects of polymer composition, assembly conditions, and the presence of halogen bond donating small molecules on the outcome of the assembly are discussed, along with NMR and X-ray photoelectron spectroscopy studies of the interpolymer halogen bonding interactions in this system.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
