Direct Arylation: A Greener Synthesis of Anthraquinone−Naphthalene diimide‐Based Small Chromophores for Applications in Organic Thin Film Transistors
Bibliographic record
Abstract
Abstract In this paper, we report the design and synthesis of three naphthalene diimide‐ (NDI) and anthraquinone‐ (AQ) based organic chromophores derived from direct arylation reactions; NDI−AQ, AQ−NDI−AQ and NDI−AQ−NDI. Compared to classic cross‐coupling reactions, this method reduced the number of synthetic and purification steps. The chemical structures, photophysical and electrochemical properties of these molecules were characterized using UV‐vis spectroscopy, fluorescence emission spectroscopy and cyclic voltammetry (CV). The optoelectronic properties of the three dyes enabled the fabrication of organic thin film transistors (OTFTs). The fabricated OTFTs displayed good n‐type semiconducting properties, with electron mobilities ( ) of 1.5–4.2×10 −4 cm 2 V −1 s −1 .

How this classification was reachedexpand
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.
