Abstract
We report passivation of CdSe and CdSe/ZnS nanocrystals (NCs) with poly( N, N -dimethylaminoethyl methacrylate) (PDMA) through a ligand exchange process. We present the results from various techniques that were used to verify that ligand exchange occurred, including 1 H NMR, 31 P NMR, and changes in solubility/colloidal properties, hydrodynamic radius, and photoluminescence. We have examined the effect of polymer molecular weight on the surface passivation and quantum yields of the NCs. As additional evidence for the binding of the polymer to the surface of the NC, we were able to modify the polymer chemically to render the NC−polymer moiety water-soluble.

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
