Triethylene Glycol Substituted Diketopyrrolopyrrole‐ and Isoindigo‐Dye Based Donor–Acceptor Copolymers for Organic Light‐Emitting Electrochemical Cells and Transistors
Bibliographic record
Abstract
Abstract Triethylene glycol, a common side chain, is attached to two different dye moieties, diketopyrrolopyrrole (DPP) and isoindigo (II), and their bromo derivative monomers are copolymerized, respectively, with common bisstannyl alkylated bithiophene via Stille coupling. The resulting donor–acceptor low‐bandgap copolymers, namely, PTDPP‐DT and PTII‐DT, are rationally deigned and synthesized conjugated polymeric systems suitable for doping. Both polymers are successfully investigated as single‐component and composite‐system‐based electrochemical transistors and light‐emitting electrochemical cells. A PTDPP‐DT thin film exhibits relatively high electrical conductivity of up to 80 S cm−1 in the electrochemically doped state, whereas PTII‐DT thin film prevents the macroscopic charge transport due to a large‐scale crystalline disorientation. Upon evaluating both polymers as active conjugated materials in light‐emitting electrochemical cells, they both exhibit emission under efficient electron/hole doping conditions.

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.
