Tuning the Photophysical Properties and Solid‐State Organization of Perfluorophenyl‐functionalized Dithieno[3,2‐<i>b</i>:2′,3′‐<i>d</i>]phospholes
Bibliographic record
Abstract
Abstract A series of perfluorophenyl‐substituted dithienophosphole derivates has been synthesized. Investigation of their photophysical properties, as well as their organization in the solid state reveals that these properties can be manipulated via introduction of bromine substituents in 2,6‐position of the dithienphosphole scaffold, as well as the complexation of the phosphorus center with an electron rich gold(I) fragment. The strongly electron‐withdrawing character of the perfluorophenyl‐group surmounts the effect of the oxidation of the phosphorus center with respect to photophysics, leading to leading to optoelectronic features similar to those of the trivalent phosphole species. The trivalent phosphole species. The solid‐state organization of the members of this perfluorinated dithienophosphole family, on the other hand, strongly depends on the heteroatoms present within the system, as close intermolecular interactions can be observed between varieties of different atoms (Au‐Au, Br‐Br, Br‐O, Br‐C, F‐C, O‐S), next to regular C‐C π‐stacking interactions.

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.
