Chemical Modifications to Structurally-Simple Low Molecular Mass Organogels
Bibliographic record
Abstract
1,3:2,4 Dibenzylidene-D-sorbitol (DBS) is the gold-standard for low-molecular-weight organogelators (LMOG). Derivatives of DBS and dimethyl urea, the smallest known LMOGs, have been developed to isolate and determine which molecular features are essential for organogelators to form self-assembled fibrillary networks (SAFiNs). For this study, π-π stacking and hydrogen-bonding are the primary non-covalent interactions that are examined. It is expected that π-π stacking is a strong contributing factor towards gelation. The synthesis and testing of 1,3:2,4 dicyclohexanecarboxylidene-D-sorbitol (DCHS), removed π-π stacking potential, but conserved all other aspects of DBS, giving an excellent basis for comparison. DCHS was found to form a gel in 1 of 23 solvents as compared to DBS which managed to form gels in 17 of 23 solvents.

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.
