Abstract
Abstract N‐type organic semiconductors are particularly susceptible to degradation by ambient air. One such solution to this issue is to include additives in the inks these semiconductors would be cast from that would enhance device stability after film deposition. This method would reduce the number of processing steps needed to fabricate devices compared to other stabilization methods, such as encapsulation. In this study, the stabilization of n ‐type performance of the semiconductor poly{[N,N′‐bis(2‐octyldodecyl)‐naphthalene‐1,4,5,8‐bis(dicarboximide)‐2,6‐diyl]‐alt‐5,5′‐(2,29‐bisthiophene)} (P(NDI2OD‐T2)) when it is blended with an increasing proportion by weight of poly(2‐vinylpyridine) (P2VP) is reported. The simple synthesis of P2VP also makes it an ideal candidate material for large‐scale applications. Concentrations as low as 0.1% P2VP incorporated into the P(NDI2OD‐T2) blends provided an immediate stabilization effect, and at 10% and 50%, longer‐term stability after one week is observed.

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 it
