Abstract
Abstract Solid‐state luminescent materials are essential for the development of optoelectronic devices like lasers, sensors, and organic light‐emitting diodes. Organic molecules reveal several benefits like stability, costs, and environmental compatibility compared to metal‐based materials. As common organic fluorophores often suffer from aggregation‐caused quenching, different strategies have been established to overcome this quenching, which are mainly based on intramolecular modifications. Controlling the photophysical properties via intermolecular interactions is more challenging and less investigated. The formation of excited dimers (excimers) bears great potential for obtaining efficient solid‐state luminescent materials. As the excimer‐formation process is strongly dependent on the non‐covalent interactions, a full understanding of the structure–property relationship is essential. In this study, structurally simple thiophosphoranyl anthracene excimers and the dependency of the photophysical properties on the solid‐state arrangement are investigated. Through crystallization of polymorphs and co‐crystals, the resulting intermolecular interactions have been modulated over a broad range. Novel insights into the excimer formation factors and the dependence of the photophysical properties on the intermolecular interactions are obtained. This study will help in the development and controlling the photophysical properties of solid‐state luminescent materials.

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
