Abstract

fetched live from OpenAlex

Abstract In this paper, we described the design, synthesis, and characterization of two novel naphthalene diimide (NDI) core‐based targets modified with terminal fullerene (C 60 ) yield – so called S4 and S5 , in which NDI bearing 1 and 2 molecules of C 60 , respectively. The absorption, electrochemical and thin‐film transistor characteristics of the newly developed targets were investigated in detail. Both S4 and S5 displayed broad absorption in the 450–500 nm region, owing to the effect of conjugation due to fullerene functionalities. The electrochemical measurement suggested that the HOMO and the LUMO energy levels can be altered with the number of C 60 units. Both S4 and S5 were employed as organic semiconductor materials in n‐channel transistors. The thin film transistor based on S4 exhibited superior electron mobility (μe) values ranging from 1.20×10 −4 to 3.58×10 −4 cm 2 V −1 s −1 with a current on‐off ratio varying from 10 2 to 10 3 in comparison with the performance of S5 based transistor, which exhibited μe ranging from 8.33×10 −5 to 2.03×10 −4 cm 2 V −1 s −1 depending on channel lengths.

Full frame distilled prediction

Teacher imitation

Not 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.
