Preparation of Two Luminescent Complexes: AlIII(8-hydroxyquinolinolato)3 and EuIII(thenoyltrifluoroacetonato)3(1,10-phenanthroline)
Bibliographic record
Abstract
A simple procedure for the syntheses of two luminescent compounds, which are widely used in organic light-emitting diodes, is presented. This experiment is suitable for an undergraduate inorganic laboratory. The two compounds are a main group coordination compound AlIIIq3, where q is 8-hydroxyquinolinolato, and a lanthanide coordination compound EuIII(tta)3(phen), where tta is thenoyltrifluoroacetonato and phen is 1,10-phenanthroline. These compounds demonstrate two types of luminescence, ligand-centered emission in AlIIIq3 and ligand-enhanced π to π transitions in EuIII(tta)3(phen). Furthermore, this experiment demonstrates the role of chelating ligands in the formation of complexes and luminescence.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
