Viable Regiochemical Control in Semiconducting Polymers for Field-Effect Transistors: From High-Mobility Enhancement toward High Deformability
Bibliographic record
Abstract
The molecular properties of semiconducting polymers with regioisomeric structural factors can be effectively tuned based on their regiochemistry. Thus, the molecular dynamics, intermolecular stacking, and film morphology of these polymers have been tuned via regiochemical control to ultimately enhance their electronic properties in organic field-effect transistors (OFETs). This strategy can also be employed to induce high deformability in organic electronics. In this review, studies on the regiochemistry of conjugated polymers based on the dimensions of regiochemical factors and synthesis methods are summarized to enable the control of the regiochemistry of substituents, side chains, and backbone linkages that can impact their optoelectronic properties and solid-state morphologies. Moreover, technological developments in the fabrication of OFETs with highly enhanced mobility toward stretchable electronics have been discussed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
