Synthesis of Novel Polyamidoamine Dendrimers with Ethylene Diamine Tetraacetic Acid as a Core
Bibliographic record
Abstract
A series of novel dendritic polyamidoamines(G0.5,G1.0,G1.5) were synthesized by amidation and Michael addition reaction step by step divergently,using ethylene diamine tetraacetic acid as the initiated core,ethylenediamine and methyl methacrylate(MMA) as the raw materials.The structures were characterized by1H NMR and IR.The optimum raw material ratios of synthesizing G0.5 and G1.5 were 1 ∶ 24 and 1 ∶ 40,respectively.The yield of G1.0 was 85.7% under the optimum reaciton conditions[G0.5 12.829 mmol,n(G0.5) ∶ n(MMA) = 1 ∶ 16,at 40 ℃ for 24 h].
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
