Binary Macromolecular Mesocrystals via Designed Block Copolymer Blends
Bibliographic record
Abstract
The theoretical prediction that various binary macromolecular mesocrystals composed of A and C spheres could be formed by B 1 AB 2 CB 3 pentablock terpolymers ( JACS 2014, 136, 2974–2977) offers a promising route to fabricate these intricately structured nanomaterials. However, experimental realization of this strategy has been impeded by the requirement of synthesizing precisely designed pentablock terpolymers. Here, we propose a conceptually new and technically simpler route to engineer binary macromolecular mesocrystals by using BA′/ABC/C′B ternary block copolymer blends that are designed to replicate the phase behavior of B 1 AB 2 CB 3 pentablock terpolymers. Using self-consistent field theory, we show that the ternary blends exhibit similar self-assembly behaviors as the pentablock copolymers, forming various mesocrystals with controllable coordination numbers. This study offers a simpler alternative to fabricating novel macromolecular mesocrystals and introduces a general design principle for emulating multiblock copolymers by block copolymer blends.

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; both teacher heads agree on what is shown here.
