The photoinduced dynamics of X[M(dmit)<sub>2</sub>]<sub>2</sub>salts
Bibliographic record
Abstract
Abstract We review our work on the photoinduced dynamics of X[M(dmit) 2 ] 2 salts in the charge-separated (CS) phase from the viewpoints of both electronic structural change and lattice or molecular structural change. The driving force for the CS phase formation is a strong correlation among the charge distribution, orbital energies, and the molecular structure; this is in contrast to frequently studied charge-ordered systems such as EDOTTF 2 PF 6 , whose formation is mainly driven by the intersite Coulomb repulsion. Despite the localized nature of the structural component, the cooperativity inherent to the crystal is likely to play an important role in photoinduced phenomena. In this review, we summarize the results obtained by a series of optical pump-probe experiments on this class of materials. We have also recently extended these studies using ultrafast electron diffraction to follow the nuclear motion in one of these systems. Such information is crucial for a full understanding of the photoinduced phenomena and it is anticipated that combining the results of the optical and diffraction studies will lead to more fruitful insight than either technique can offer in isolation.

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.
