The Influence of Solvent on Complex Formation of Crown Ether with Tetraphenylphosphonium Chloride
Bibliographic record
Abstract
The host guest interactions of crown ether (18-C-6) with tetraphenylphosphonium chloride (TPPC) were studied in different solvents at 303.15 K. The values of reaction enthalpies, ΔH0, and equilibrium constant, K, have been calculated and the results show that solvation of tetraphenylphosphonium ion (Ph4P+) is not very important. Because the cavity of the 18-C-6 is too small to completely accommodate large Ph4P+ ion. Thus, the interactions between the cation and the oxygen donor atoms of the ligand decrease, the large cation is surrounded by large organic moieties which interact more strongly with the organic environment and therefore it will not have tendency to form complex in non-aqueous solvents.

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.
