Abstract

fetched live from OpenAlex

The semiempirical INDO calculations were carried out to investigate the charge-transfer interaction and to evaluate the second-order nonlinear susceptibilities for a series of fulleropyrrolidine–tetrathiafulvalene(C 60 PY–TTF) dyads, C 60 PY, and C 60 PY-(CH=CH) n -TTF (n = 0–6). The equilibrium geometries, electronic structures, and UV–vis spectra of these C 60 PY–TTFs D–B–A dyads were determined by using ZINDO methods. On the basis of electronic spectra, we calculated the β for the dyads using the ZINDO-SOS expression, and found that these dyads have relatively large β. The calculated values of β are 48.78, 62.34, 97.90, 123.24, 183.78, 189.43, 193.45, 195.82 × 10 –30 esu for C 60 PY and C 60 PY-(CH=CH) n -TTF (n = 0–6), respectively, which shows the enhancing effect when TTF is introduced. The β significantly increases as n increases from 0–3; and it tends to be saturated in the end.Key words: ZINDO-SOS, CI, structure, spectra, C 60 PY–TTF.

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.
