Amide-Containing Alkyl Chains in Conjugated Polymers: Effect on Self-Assembly and Electronic Properties
Bibliographic record
Abstract
A simple and efficient strategy to modulate the self-assembly and solid-state morphology of conjugated polymers has been developed by incorporating various amounts of amide-containing alkyl side chains to high charge carrier mobility conjugated polymers based on diketopyrrolopyrrole (DPP). Synthetically easily accessible and tunable, the incorporation of amide-containing side chains is a direct strategy to promote intermolecular hydrogen bonding between polymer chains and tune the solid-state morphology. Incorporation of 5–30 mol % of amides in the conjugated polymers was performed without a drastic decrease of solubility. The incorporation of hydrogen-bonding moieties allowed for an improvement of the charge carrier mobility in organic field-effect transistors (OFET) devices, which achieved a maximum value of 2.46 cm 2 /(V s) at 5 mol % of amides. Morphological investigation showed that the intermolecular hydrogen bonds formed between adjacent amide moieties directly affected the lamellar packing of the polymer and aggregation, without affecting the π-conjugation. Therefore, controlled self-assembly of conjugated polymers through hydrogen-bonding side chains is a promising strategy toward more efficient semiconducting polymers for thin film transistors and other organic electronics.

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.
